…unds (#47327) Closes #47157 This panic happened because the editor was using `window.content_mask` to get the visible bounds, which had a negative value for its height in some cases. This happened for three reasons: 1. `Bounds::from_corners` returns a negative size if callers pass in corners where `bottom_right < top_left`. I originally wanted to add error checking to this function but didn't, because it might be better to move the error checking higher up. For now I'm going to push a fix and figure out a better solution later 2. `Bounds::intersect` could return negative-sized bounds when the two bounds didn't overlap, instead of returning a zero sized bounds. 3. `Style::paint` sometimes passed invalid corner values to `Bounds::from_corners` (where the computed bottom-right was above/left of the top-left).

Cherry-pick of #47327 to preview
Closes #47157
This panic happened because the editor was using
window.content_maskto get the visible bounds, which had a negative value for its height in
some cases.
This happened for three reasons:
Bounds::from_cornersreturns a negative size if callers pass incorners where
bottom_right < top_left. I originally wanted to adderror checking to this function but didn't, because it might be better
to move the error checking higher up. For now I'm going to push a fix
and figure out a better solution later
Bounds::intersectcould return negative-sized bounds when the twobounds didn't overlap, instead of returning a zero sized bounds.
Style::paintsometimes passed invalid corner values toBounds::from_corners(where the computed bottom-right was above/leftof the top-left).
Release Notes:
is zero
