Fix CI test failure which started happening in this test after the
addition of Window::ContextHelpCaptureLost in e04e3260fc (Handle
context-help mouse capture loss, 2026-07-08) because the child window
that was not supposed to be repainted still was, as the entire window
needed a refresh.
Refresh and update it before starting the test to make it pass again
reliably.
