The audio clip can be played after it's been removed from a looped region of an audio track

### Bug description

So basically I was messing around with Audacity's features, and came across a bug that is possibly not known by the developers, what I'm talking about is that Audacity can somehow magically play non-existent files, like they are still there.

### Steps to reproduce

1. Load/generate an audio clip
2. Select and copy a portion of the clip or the clip as a whole
3. Paste the copied audio clip anywhere onto the same audio track
4. Ctrl (Cmd) + A, then enable Looping
5. Select the just pasted audio clip
6. Delete the clip selected, and click Play

### Expected behavior

No sound when playing the audio track

### Actual behavior

Audacity will play the deleted clip and then loop back to the original clip
