Research direction

Read lib/extension/window.js, especially warpPointerToNodeWindow, and check how it obtains the default seat under GNOME Shell 51. The issue includes a proposed change from Clutter.get_default_backend() to global.stage.context.get_backend() and logs showing the current call fails. Verify the pointer follows focus on GNOME Shell 51 and that the existing behavior still works on supported versions.

Hello,

Since gnome 51 (on fedora 45) the mouse does not follow the focus anymore.
This fixes it.
