WindowDraggableArea has a problem (jumps to bottom on click)

[mahozad]

Describe the bug Occasionally, clicking on an undecorated window that has a custom title bar (using WindowDraggableArea) causes the window to jump to bottom.

This happens every so often and may not be so easy to reproduce.

Here are two times that I reproduced the problem:
