Fix #29881 - Stopped left over slides from being applied to rests
Fix #29946 - Input via mouse in TAB's disrupts inpur cursor position
Starting playback while in entry mode should exit entry mode.

Currently, starting playback while in entry mode does not leaves entry mode on, even if entry is actually impossible during playback.

In addition, when playback stops, entry mode (which is still on) is not stable and lacks an input cursor.

This fix shuts down entry mode altogether when starting playback.
