I would like to do a soft fullscreen for a html5 game. In previous iOS version, I can create a dummy scrollable element to allow user to scroll the page and hide the address bar. Once the address bar is hidden, I can disable the scroll to make it stay in fullscreen.
However, I found that the behaviour in iOS15 safari has changed. I can still scroll down to make it fullscreen, but since iOS15 safari has a default swipe down gesture to show back the address bar, the page cannot keep in fullscreen when user swipe down (scroll up). Is there any way to disable the default swipe down gesture in iOS15 safari?
