The test ResizingFrameTest fails with:

java.lang.RuntimeException: No Mouse Entered/Exited events!

It looks like the mouse pointer is no longer in the right place from the XWayland server's point of view after calling
frame.setExtendedState(Frame.MAXIMIZED_BOTH);

E.g we have
```
robot.mouseMove(500, 500);
...
System.out.println(MouseInfo.getPointerInfo().getLocation()); // java.awt.Point[x=500,y=500]
...
frame.setExtendedState(Frame.MAXIMIZED_BOTH);
...
System.out.println(MouseInfo.getPointerInfo().getLocation()); // java.awt.Point[x=856,y=463] or other location depending on actual mouse cursor position on system
...
robot.mouseMove(500, 500); // has no effect
...
System.out.println(MouseInfo.getPointerInfo().getLocation()); // still doesn't print 500, 500
```
