Steps to Reproduce

On URL https://zkfiddle.org/sample/3l8gc4h/7-confirmClose is sample.

Current Result

When you press the button "Apply confirm close" and try to close the tab, a confirmation dialog will appear. If the "Stay on page" option is selected, the folder will not be closed (so far everything is fine), but the test window cannot be closed anymore. Another application of mine behaves similarly: sending events from components stops working.

Expected Result

After the confirmation dialog is displayed and the "Stay on page" option is selected, the application will continue to be operable.
