displayOverlay doesn't disappear after timeout #27082 Fixes #26555 ### Expected Behaviour An overlay should be displayed atop an image and then disappear after `delayms` has timed out, but it doesn't. Also, `displayStatusBar` doesn't appear to set any text on the window. ### Actual Behaviour The overlay appears but doesn't disappear unless a mouse move event happens on the image. ### Changes - Fixed the issue with `displayOverlay` not disappearing after the timeout. ### Checklist - [x] I agree to contribute to the project under Apache 2 License. - [x] To the best of my knowledge, the proposed patch is not based on a code under GPL or another license that is incompatible with OpenCV. - [x] The PR is proposed to the proper branch. - [x] There is a reference to the original bug report and related work. - [ ] There is accuracy test, performance test, and test data in the opencv_extra repository, if applicable. - [ ] The feature is well documented, and sample code can be built with the project CMake.
