[PATCH v4 0/3] MR6608: riched20: Only run editor_ensure_visible and ME_SendRequestResize when control is in-place active.
According to microsoft documentation, GetClientRect, ScrollWindowEx, SetScrollPos and SetScrollRange (among others) may only be called while the control is in-place active.
This fixes a segmentation fault in Anytone CPS.
-- v4: riched20/tests: Test that ScrollWindowEx and GetClientRect are only called when control is in-place active. riched20: Only call ME_SendRequestResize when control is in-place active. riched20: Exit from editor_ensure_visible when control is not in-place active.

According to microsoft documentation, ScrollWindowEx, SetScrollPos and SetScrollRange may only be called while the control is in-place active.

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:
The full results can be found at: https://testbot.winehq.org/JobDetails.pl?Key=148836

Looks ok. Could you re-order the commits so that the tests come first (with added `todo_wine`s on the tests that'll fail). Then follow with the implementation changes, removing `todo_wine`s as appropriate. That way it's clear that your changes do indeed fix the tests that you're claiming they do.
Also, it's no long necessary to add `Signed-off-by` tags.
