What is the bug or the crash?

After I edit a labelling expression in the Layer Styling panel, using undo and redo will undo and redo that change, but the map canvas will not refresh.

The same if I check or uncheck "Draw background", or "Draw text buffer". I guess all labelling changes are not refreshed with undo or redo...

Steps to reproduce the issue

see description above
