Subject: [PATCH] Fix focus/blur unit test issues. Reopens #6705.

In the event refactor, I tried to have the focus/blur events trigger the focus/blur plus focusin/focusout events but this doesn't handle various real-world cases that expect a trigger()ed jQuery handler to run and be able to pass data even if the native event shouldn't fire.

This reopens a bug that causes a double-fire of
inline event handlers.
