There are now [figma specs](https://www.figma.com/file/FjUe6ORvXZgJvI3rPuTV33/Desktop-UI-(Mozilla-Confidential-)?node-id=11553%3A58264) that indicate short windows have modals positioned higher but never overlapping tabs or urlbar toolbars (so bookmark toolbar and infobars can be covered).

This behavior seems to be pretty close to the pre-MR1 behavior where the panel(?) is not contained by the window although top anchor point is different. In 88, it's somewhat centrally aligned and goes no higher than the bookmark toolbar as the window shrinks.

Is it difficult to switch to the old behavior? If not "like a panel" for MR1, emanuela did suggest "do the “max overlaps” and then scrollbar for right now." Although "max overlaps" doesn't specify a minimum bottom spacing as the desired behavior is to have it extend, so maybe we just need to pick something reasonable, e.g., match the top edge or maybe just 1em or a fixed px.

This is also while allowing the bottom to extend out below the window.
