How to reproduce it:

1. build the attached application
2. run it
3. there is a main window that has a push button "Open Dialog". Clicking the button opens a dialog. The dialog has a "Show Popup" button. The dialog has a grey background to make it clear which part of the screen is Dialog and which is MainWindow.
4. clicking the button opens a popup - in this case it is a QMenu. The menu contains a single item showing the Qt version.

Current result : touching on the MainWindow doesn't close the popup on eglfs
Expected result : the same behavior as , on desktop or 4.8, that touching anywhere on the application (MainWindow or Dialog) closes the popup and focus returns to the dialog.
