Before this commit, on a clear session, there was a traceback after focusing out the emoji button next to the composer. This is due to a DOM element that exists only after clicking on the emoji button, and it was wrongly assumed that focusout cannot occur without a preceding click. Indeed, we can press TAB to move between focusable elements, so that we can have the focus in/out on the button without clicking on it.
