Describe the bug
When a window changes from maximized state to Normal state, it fails to restore the ClientSize of the Normal state.
To Reproduce
This triggers the Resize event twice:
First trigger: The Reason is Unspecified, and the ClientSize value correctly reflects the previous Normal state’s ClientSize. Second trigger: The Reason is Layout, but the ClientSize value becomes abnormally large, approximately matching the ClientSize during the maximized state
