if first event in day was hidden, the date sep would go missing as the next event would compare its date to the hidden one instead of the one before it
due to naive N-1 check rather than a previous valid event comparison, now fixed by comparing date against the first event in MELS instead.

This code only kicks in if the user was ignored after an event was sent. The homeserver should prevent other events from coming in.

Use `react-sticky` to implement sticky date separators. This will pin a date separator to the top of the timeline panel when the separator scrolls out of the top of the view.
A known issue of this is that the spinner, which is in line with event tiles in the timeline, will appear to push the stuck date separator down. In reality the first date separator after the spinner is in line with event tiles and is not stuck because the spinner forces the timeline to be scrolled slightly further down than it would be otherwise. But also, date separators in the timeline (not "stuck") have a greater height.
Ideally the date separator would be suppressed whilst back paginating, but this will cause the stuck separator to flicker on and off. This is why the suppression has been removed.
this fixes the scenario of N Member events, then an invisible event
e.g. (m.room.aliases) then more Member events. Pre hide-join-parts
this is how it worked.

do not have the same i reference (namely MELS generation)
this way a member event at bottom of MELS (if is the last event
in the timeline will have last set appropriately)
refresh, this may need to be handled differently in the future.
Currently handling same as the new timestamp stuff

- Instead of using one attribute, use one that might just contain one token
- Use the first token when tracking a child
- Mandate that no commas can be in individual tokens
This adds the `data-contained-scroll-tokens` API to elements in `ScrollPanel` which allows arbitrary containers of elements with scroll tokens to declare their contained scroll tokens. When jumping to a scroll token inside a container, the `ScrollPanel` will act as if it is scrolling to the container itself, not the child.
MELS has been modified such that it exposes the scroll tokens of all events that exist within it.This means "Jump to unread message" will work if the unread event is within a MELS (which is any member event, because even individual member events surrounded by other events are put inside a MELS).
Put a XXX to indicate that the ghost tile should be replaced with something mor e stable. As it stands, the ghost will appear, potentially at a different position to the RMs actual position
To fix https://github.com/vector-im/riot-web/issues/2916, force the checking of scroll position by calling _onWidgetLoad (might need renaming...) when a MELS is expanded/contracted.
Also use an keying scheme for MELS that doesn't depend on the events contained, but rather a simple incrementing index based on the order of the MELS as it appears amongst all MELS.
The MELS can now deal with arbitrary sequences of transitions per user, where a transition is a change in membership. A transition can be joined, left, invite_reject, invite_withdrawal, invited, banned, unbanned or kicked.
Repeated segments (modulo 1 and 2), such as joined,left,joined,left,joined will be handled and will be rendered as " ... and 10 others joined and left 2 times and then joined". The repeated segments are assumed to be at the beginning of the sequence. This could be improved to handle arbitrary repeated sequences.
This was causing rendering of MemberEventListSummary to be quite slow. Instead of creating two date objects, just check to see if they represent timestamps that happened on different days.
- The MessagePanel now uses the same key for the MELS instances rendered so that entirely new instances are not created, they are simply passed new props (namely when new events arrive).
- MELS itself now uses `shouldComponentUpdate` so that it only updates if it is given a different number of events to previous or if it is toggled to expand.
* Fix join/part collapsing regressions
* Simplify loop
* Explain e,e
* Explain return null in _renderSummary
* Kill it properly
* Move . to _renderSummary
* Only use the first and last events to decide whether a net change has occured
* Do not sort events by TS before summarising
* fix loop and comment
* remove data-number-events
* Better explanation comment in _renderSummary
* Less tortuous comment
Instead of using a window of a fixed number of events, unpaginate based on the distance of the viewport from the end of the scroll range.
The ScrollPanel uses the scrollTokens to convey to its parent (the TimelinePanel, in this case) the point to unpaginate up to. The TimelinePanel then takes a chunk of events off the front or back of `this.state.events` using `timelineWindow.unpaginate`.
Fixes https://github.com/vector-im/vector-web/issues/2020
1) Correct fix for Velociraptor (we need to find the DOM node and pass that in)
2) Do the same leak fix for the read marker
3) Update the dependency to our fork which is fixed to make the call we do to release memory actually work.
4) Remove the velocity-ui-pack dependency which is unnecessary because velocity-ui is included in the velocity package
... hopefully fixing https://github.com/vector-im/vector-web/issues/1437 in the
process.
The idea here is that, when we remove a read-receipt from the DOM, we stash its
position in a map. Then, when the read-receipt appears again attached to
another event, we know where to start the transition.
Each individual eventtile isn't particularly expensive, but when you have 500
of them, they start adding up. Shuffle some of the stuff into MessagePanel, so
that we can shouldComponentUpdate EventTiles properly.
I think this was responsible for the readmarker just disappearing rather than
animating.
While we're here, decrease the delay on the animation, and instead make it take
slightly longer to disappear.
This fixes an issue where the RM appeared before any events which were pending
when you switched away from that room
(https://github.com/vector-im/vector-web/issues/1241).
Also, fix a buglet in the MessagePanel which meant we didn't animate the
disappearance of a RM when it stayed at the same event but became
invisible. This didn't really cause any user-visible problems (because
typically we advance the RM at the same time as it became invisible), but
confused me a bit while I was trying to debug this.
Rather than telling react-gemini-scrollbar to update every time something that
changes its size happens, try out our fork of it which uses some hackery to
listen for resizes.
We need two modes of operation for ScrollPanel.scrollToToken:
For jump-to-read-marker, we want it 1/3 of the way down the screen.
For search clickthrough, and hyperlinked events, we want put the event in the
*middle* of the screen.

Make the onImageLoad handler call checkScroll on the right thing. This was
originally done in commit 99d2392, but got broken in the Great RoomView
Refactor of February 2016.
