The following patches fix sending of the LVN_ODSTATECHANGED notification for LVS_OWNERDATA list views, adding more refined tests in the process and fixing various bugs. This is v5, with the added comment in 3/6 as requested on the mailing list. These are the patches sent as a response to v4 by Zhiyi Zhang on the mailing list, unmodified apart from 3/6 or f24f4b7fd. --- Warning: I have had access to the Windows Research Kernel (WRK) 1.2 ~10 years ago. These changes are regarding comctrl32 & tests which are NOT part of the WRK. As outlined in https://wiki.winehq.org/Developer_FAQ this should therefore satisfy the requirement of ONLY submitting patches to components I have NOT had access to. -- v4: comctl32/tests: Add more ownerdata listview tests. https://gitlab.winehq.org/wine/wine/-/merge_requests/550
