MouseListener does not work on Windows after hide/show #368
Description
Original report by Anton Tarasov (Bitbucket: Anton Tarasov).
MS Windows. JCEF 81.2.24+gc0b313d+chromium-81.0.4044.113
The test is modified to print mouse (motion) events on the browser UI component. Also the “Hide and show” menu item hides and shows the browser component.
- Run the test.
- Keep moving mouse over the browser - see the mouse events printed.
- Select from the menu: Tests > Hide and show
- Repeat the 2nd step - see the mouse events no longer printed.
