|  * This is meant to be a cache of room alias to room ID so that moving between

 | |
|  *
 | |
|  * 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.
