Increasing sleep times in test has no effect and it looks like we have some product bug for Ubuntu24.04.
This behaviour is seen in both Wayland and Xorg in Ubuntu 24.04.

Fails with same exception on Ubuntu 24.04.1 but not on Ubuntu 22.04.5.

Looks like when we change full screen window back to non-full screen one it is not returning to its original dimension.
