The bottom sheet has an animation where it starts off-screen and animates in. At the same time it moves focus into itself. It seems like under certain conditions (e.g. having
backdrop-filter
on thebody
) this causes the entire page the jump in a jarring way due to the focus being moved.These changes resolve the issue by telling the browser not to scroll the page when moving focus.
Fixes #30774.
