/**
|

|
|
* This is meant to be a cache of room alias to room ID so that moving between
|
||
|
|
* rooms happens smoothly (for example using browser back / forward buttons).
|
||
|
|
*
|
||
|
|
* For the moment, it's in memory only and so only applies for the current
|
||
|
|
* session for simplicity, but could be extended further in the future.
|
||
|
|
*
|
||
|
|
* A similar thing could also be achieved via `pushState` with a state object,
|
||
|
|
* but keeping it separate like this seems easier in case we do want to extend.
