The fix for bug 40339 supposedly modified when we emit contextChange events so that when the node changed, even if the context was the same, we consider it a context change (such as changing the heading level).
Unfortunately I was mentally absent when I wrote the patch and all it actually does it emit more select events.
Basically cb4877b0d0 - which does indeed fix the bug - doesn't do what it's commit message describes, but this fixes it.
