With this patch, the back-to-the-main-keyboard in the Emoji
palette will be registered as a key-release action instead of
a key-press action, like switch-to-the-emoji-palette in the
main layout. This provides mroe consistent UX when the layout is
switched from the main layout to the Emoji palette then
switched back to the main layout.

The old logic only checks the top 3 suggestions before the
final adjustment. It leads to instability in scores.

On the Emoji palette, unlike other layouts, a user could not
cancel events by moving the finger away from the spacebar.

With this patch, the actual handler of the spacebar will be
registered as onClick event, which will not occur when the user
cancel the event.
