Subject: Preview and math now update on screen-up (#6173)

Preview and math now update on screen-up (#6173)

When editing a preview inset, or math, when we leave the inset, we
should update the preview. This update now happens for screen-up and
screen-down (commonly bound to Page Up and Page Down).

Note that this is only relevant if preview is turned on in
preferences.

This commit probably fixes other issues for any inset that defines
notifyCursorLeaves().

This fixes only part of #6173.
