Time and measure counters continue to run after end of piece (for 3 seconds)

Describe the bug

Even when the piece has ended on the score page, the time and measure counters continue to run for another measure or so.

There are also problems at the end of the score when you add a tempo mark at the beginning.

To Reproduce

1. Open the short example score and play it through.
   playback_issue.zip

RESULT: When the playback cursor has reached the end of the score and audio playback has finished, the time and measure counters are still running and do so for another 7 beats.

2. Add a tempo mark from the palette (not shortcut as there is a bug – see #13662).
3. Play back again.

RESULT: Playback continues for a while after the end of the score is reached, and the time and measure counters continue to run.

Expected behavior

Playback and the time and measure counters stop at the end of the score.
