[PATCH v3 0/2] MR6218: comctl32/treeview: Allow treeview parent to deny treeview expansion.

[Jacob Czekalla (＠JacobCzekalla)]

When the listview expands or collapses an item it notifies the parent using the TVN_ITEMEXPANDING message. The parent can return true on this message and it prevents the treeview from expanding or collapsing the item. WINE does not let you deny TVN_ITEMEXPANDING by returning true.

Hi,

It looks like your patch introduced the new failures shown below.
Please investigate and fix them before resubmitting your patch.
If they are not new, fixing them anyway would help a lot. Otherwise
please ask for the known failures list to be updated.

The tests also ran into some preexisting test failures. If you know how
to fix them that would be helpful. See the TestBot job for the details:
