If a Window containing a WebEngineView is moved from screen A to screen B the HTML element <select> displayed by the WebEngineView will stop functioning. It will no longer expand (at least) in a manner that would be visible to the user. This can occur at least under following conditions:

• screen A resolution is smaller than screen B
• screen B has resolution of 3840x2160
• high dpi scaling enabled for the app
• screen B scale factor set to 150%

Steps to reproduce the problem:

(check the attached video for reference)

1. Start the example so that the app window appears on screen A
2. Drag the window to screen B
3. Click on the select element

NOTE: The same problem could not be reproduced with QWebEngineView. Only the Qml counterpart.
