DnD: drop performs to a wrong window from X11 client on Wayland

Affected version

Fedora 36 (Rawhide) / GNOME Shell 42.alpha

Bug summary

Can't perform a Drag and Drop operation from X11 client to a Wayland client if there is an intermediate window during the drag.

Steps to reproduce

1. Compile and run X11 client XDnDSource.c by gcc XDnDSource.c -o XDnDSource -lX11 && ./XDnDSource
2. Place windows like this:
   
   Where:
   1. Our DnD source an X11 client.
   2. terminal window
   3. gedit window
3. Try to perform DnD from Window#1 to Window#3 over Window#2

What happened

Text is dropped to Window#2

What did you expect to happen

Text is dropped to Window#3

Relevant logs, screenshots, screencasts etc.

Success on X11: x11.log
Failure on Wayland: wl.log

This case may be sometimes successful though if you switch Window#1 and Window#3 positions(gedit on a left side, X11 source on the right, it may fail for me depending on drag speed).

Success on Wayland: wlSuccess.log

This issue also can be reproduced with example from Gtk3 Python tutorial(with GDK_BACKEND="x11" set and text radio button selected).
