Deleting all text in edit mode breaks Undo

1. Open any score that contains text elements (e.g. the attached).
2. Double-click on the text to edit it, and delete everything inside it (Ctrl+A, Del)
3. Confirm by leaving text edit mode (Esc).
4. Undo (Ctrl+Z) to try to restore the text deleted in step 2.

Result: Nothing seems to happen. The text element gets selected and still exists, but remains empty (and invisible). The deleted content is lost and cannot be restored with Undo.

• Other actions performed before or after deleting the text are not affected and can still be un/re-done.
  This includes changes to the content of the very same element!
• All text elements I have tried are affected.
  • For lyrics and chord symbols, it does not seem to matter how I confirm my edit (leaving edit mode Esc, or jumping to another element with e.g. Space).
  • EDIT: Text frames are not affected (Undo works as expected); but text added to vertical or horizontal frames is affected.
• Undo works as expected if the text is instead replaced by any non-empty text before confirming (including entirely whitespace), or if the whole element is deleted outside of edit mode.
