           Summary: Context menus may be positioned using the wrong window

Log output while opening context menus in nested, reparented windows
Context menus do not open in the expected location.
Since 9.22, there was a mouse bug (#57603) affecting yabridge-host.exe, an X11
bridge which uses several reparented windows to show a VST/CLAP plugin running
in Windows inside of a Linux DAW view: Mouse events (clicks, etc.) were being
located using the entire screen, and the small plugin window was using this
(fullscreen absolute) coordinate from its origin to remap each mouse event.
In clearer terms, a plugin window dragged to the upper-left of the screen would
function normally. Drag the window right by five centimeters, and mouse events
would land five centimeters right of the cursor.
While there have been patches and a merge request
(https://gitlab.winehq.org/wine/wine/-/merge_requests/7429) in progress fixing
the cursor offset, context menus now have the opposite behavior. Their position
is calculated as an offset in the smaller plugin window, and then they are
drawn with this offset from the absolute screen origin.
Open a context menu while the plugin window is in the upper-left of the screen?
It shows up in the correct place. Drag the window 5 centimeters right? The
context menu will open 5 centimeters to the LEFT of the cursor.
I am attaching a log where I open a menu, move the window to the left, and open
the menu again.
