* Focus the thread panel when clicking on an item in the TAC
actually the 'close' button in the threads panel as it's the only
interactive element: we can improve this later when we use landmarks
& generally have better a11y.
* Undo minor refactoring
as none of it is test3ed, it's not worth it.
* add unit test
* Add matrixchat tests
* Needs awaits
* ts-ignore
* Fix test (I think...)
* Remove unnecessary value set
* Not how assignments work
