Nitpicking myself this time. One _new_ problem is that all message sequence tests are gone, leaving testing for TVN_ITEMCHANGED only in the commit message. I meant to do this properly in updated test_select(), but it wasn't accepted. Right now, there's no equivalent of test_select() for Common Controls v6. I'll restore message sequence test for TVN_ITEMCHANGED. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10451#note_141785
