Revert "Capture delayed events and cancel as necessary."

Tag #1052 (backout).
Backed out for creating issues like #1191 and other issue-less problems
with e.g. losing the caret from text boxes. Of note: this was also
backed out from m-c for similar reasons in Bug 1332433.
This fixes #1191.
This reverts commit 3424afccaebc71c4acd4fa9eadf519c408c5965b.
