The behaviour of the lookahead is a bit buggy in some browsers on mobile
causing it to query the formatted result again once it's selected
resulting in an error. Editing the chosen user does not make sense (and
resets the model), hence it's better to make the field readonly after
selection anyway and allow resetting it.

element (e.g. login button blocked by toast mentioning that login has
expired).

The new ordering is as follows:
 1) events
 2) current/upcoming states
 3) past states

In each of these categories, the elements are ordered chronologically
based on start time. This is to make the most important things the
closests to the top.
