Remove DCHECKs in FloatRoundedRect::Radii::Expand()

wangxianzhu · chromium-wpt-export-bot · commit 6d14c7abcf06 · 2022-03-04T07:24:04.000-08:00
The DCHECK failed when we calculated the inner bounds of an outline with border-radius, if the outline had big negative outline-offset and was on a box whose size was bigger than 2x outline width in one dimension and smaller than 2x outline width in the other dimension. In the case, FloatRoundedRect::Radii::Expand() was called with a gfx::OutsetsF with mixed positive/negative components. Remove the DCHECK as the case is valid. Will follow up for refactors and cleanups.
