Dragging rehearsal markers makes them disappear

This is with build:

OS: macOS 15.3, Arch.: arm64, MuseScore Studio version (64-bit): 4.5.1-250800846, revision: 603eca8

Consider this test chart:

Behavior is erratic and inconsistent. But try the following:

1) open the attached file
2) find the rehearsal marker "Sax Solo - like Bridge"
3) click near the word "Bridge" and start dragging downward, perhaps slightly to the right

The rehearsal marker completely disappears. Under slightly different conditions, it might hop completely to another system or do other odd things. Very strange.

Hopefully you're able to reproduce it.
