Where: * 204 == WM_RBUTTONDOWN * 205 == WM_RBUTTONUP * 206 == WM_RBUTTONDBLCLK
Although they seem unrelated, the test_window_from_point() failure and the set of 13 test_mouse_input() failures always happen together which means they probably have a common cause.
Also these failures are usually rare but can be almost systematic at times, for instance from 2022-04-25 to 2022-05-30 on w1064 32-bit.
