Open
Description
When you open a scrollable modal with an overflow (e.g. style installer) and keep on scrolling once you reached the top/bottom boundaries you frequently end up scrolling the content in the background (either scrolling an element with an overflow or triggering the 'rubber band' effect).
The upcoming overscroll-behavior
property (https://developer.mozilla.org/en-US/docs/Web/CSS/overscroll-behavior) should address this, but it is not supported by Mobile Safari yet and testing with Chrome on iOS shows that it doesn’t work there either (even the demo example on MDN [https://mdn.github.io/css-examples/overscroll-behavior/] doesn’t work).
Is there anything we can do about this issue?
