[regression] Text: newline character can't be deleted by 'delete', only 'backspace'
- Enter a text with a newline in it (any type will do, staff/tempo/title/...)
- Put the input cursor at the end of the first line
- Press Del
Expected result: The newline character is deleted
Actual result: nothing happens
Put input cursor at the start of the second line, press backspace.
Bug present in 3.1 & 3.2, probably all 3.x's are affected.
Regression compared to 2.3.2 where this does work as expected
