1541806 - Evaluate making the EventBufferer delay actions instead of events

Status: NEW

(Firefox :: Address Bar, defect, P3)

Description

[Marco Bonardo [:mak]]

In bug 1532738, we saw how delaying events creates problems to preventDefault(), because the event handler acts too late.
A possibility to solve that better than the status-quo (double call to handleKeyNavigation), may be to delay actions instead of events, so we serve the event immediately but we enqueue the action that should follow. The Bufferer would then keep a list of {event, actionCallback}.
It may not be as straightforward though, because some of the conditions that may apply to the initial event handling, may have changed in the meanwhile, so we could have to double check the conditions before executing an action.
