iOS Chrome 119 Beta: When exiting an AR QuickLook session the originating HTML page view is broken

### Description

When exiting an AR QuickLook session, the originating HTML page is scrolled back to the top of the page, and the entire viewport is shifted down the screen making it look broken.

When using inspection tools, it appears that the entire HTML element has been shifted down the screen.

This used to work fine in previous versions where web page would not be scrolled and viewport would not be moved.
