[ PopOver-Paper ] - Opening PopOver causes the page to scroll

[guilhermeabell]

Rendering any component that internally relies on Modal, causes the page to jump/scroll.

• The issue is present in the latest release.
• I have searched the issues of this repository and believe that this is not a duplicate ([Popover] On mobile Chrome while zoomed, opening popover causes page to jump #17636 might be related though 🤔)

Current Behavior 😯

Rendering a component that is based on Modal (i.e. Popover) causes the page to scroll. This happens as long as:

• the scroll container has already scrolled
• the contents of the scroll container affect its total height

Expected Behavior 🤔

Scroll position should not change.
