[PATCH v4 0/2] MR11135: win32u/tests: add test for swp_owner_popups self-reference fix

[Jiajin Cui (＠jin-king1)]

Add test_swp_owner_popups to verify that swp_owner_popups restores
initial_after when it becomes the window itself. When an owned popup
is immediately above its owner in z-order and is moved after the
owner, the function incorrectly sets after = hwnd (self-reference).
The fix restores initial_after, and the test verifies this via
WM_WINDOWPOSCHANGED hwndInsertAfter capture.
