Description Sammy Gill 2023-02-13 12:35:42 PST

It seems like at least in certain cases floats are not being marked as dirty when going through layout again. \

imported/w3c/web-platform-tests/css/css-box/margin-trim/block-container-overflowing-float-margins-tirmmed-at-final-position-block-layout.html showcases this behavior

During the first layout the float gets its correct position, but then when a second layout occurs it gets placed incorrectly since it was not dirtied and did not go through layout again

This part of the spec was removed by the CSSWG and will potentially be explored later in a future version of the spec. As a result, this issue no longer applies at this time.
