Prior to #1912, height fix up of image events without an `info` in their
content would fail, setting `style.height = null + "px"`.
Now that all thumbnail sizing is done through one path, we can fix the
same problem for all cases (images, stickers, e2e/non-e2e) by handling
images without `info` correctly.
At the bare minimum, we use a null-guard that will make sure an image
without an `info` does not appear in the timeline (as a spinner or
otherwise until loaded). When loaded, we size it like any other image
by using the natural dimensions of the loaded image in place of `info`.
Note that we do not apply the same logic to images that *do* specify an
`info` with `w` and `h` keys. If the aspect ratio of the image does not
match that of the event, we use the one in `info` even when the image
has loaded.
The benefits of this:
- One code path for determining spinner/placeholder and it's position
for loading images/stickers. This includes spinner used in e2e
decryption of images.
- Very small definition for MStickerBody, only overriding the minimal
differences is has from MImageBody.
The disadvantages:
- Slightly more complicated MImageBody, but hopefully not less
readable.
As the slightly nicer alternative to fixupHeight being applied once
we actually have a timelineWidth.
The niceness comes from not needing timelineWidth, which means we can
implement at render time with CSS. (Despite still calculating aspect
ratios when we render.)
* Allow the client to run without connection to HS (i.e. using indexeddb)
Allows running without having pushRules (it's safe not to have these
when running from indexeddb sync.)
This means rooms will be displayed with "unknown" notifcation state.
This assumes anything that uses the push rules will get pushRule state
again when the client starts syncing again.
For recovering from being disconnected,
* If an avatar has fallen back, try again on reconnection
* If a thumbnail image failed to load, retry on reconnect
* Load joined groups when reconnecting
Update tests to give MELS a context.matrixClient
* Render attachments inside iframes.
* Fix up the image and video views
* Fix m.audio
* Comments, and only use the cross domain renderer if the attachment is encrypted
* Fix whitespace
* Don't decrypt file attachments immediately
* Use https://usercontent.riot.im/v1.html by default
* typos
* Put the config in the React context.
Use it in MFileBody to configure the cross origin renderer URL.
* Call it appConfig in the context
* Return the promises so they don't get dropped
`onWidgetLoad` is now being called when an image has been decrypted so that the ScrollPanel maintains its scroll position (whether it's stuckAtBottom or not). This attempts to fix https://github.com/vector-im/riot-web/issues/2624
* Send a thumbnail when sending a m.image
* Use the 'thumbnail_file' when displaying encrypted images
* Whitespace
* Generate thumbnails for m.video
* Fix docstring, remove unused vars, use const
* Don't change the upload promise behaviour
* Polyfill for Canvas.toBlob to support older browsers
* Lowercase for integer types in jsdoc
