Drag and drop failure animation targets wrong point

When dragging some selected text from the TextView on the widget factory's first page and dropping it over an invalid target, an animation is supposed to fly the item back to the point the drag started.

However, in my case this animation targets the wrong point. It is always somewhere in the top-left quadrant of the window so I assume the coordinates should be scaled by the buffer scale but aren't.

GTK 3.24.24 and 4.0.1 (both are affected)
GNOME Shell 3.38.3
Wayland, 3840x2160, scale 2, no scale-monitor-framebuffer
