Description Sammy Gill 2023-01-25 09:26:58 PST 
It also affects floats for which the block container is a containing block by:

- Discarding the block-start margin of any float whose block-start outer edge coincides with the block-start inner edge of the container.
- Discarding the inline-start/inline-end margin of an inline-start/inline-end float (or equivalent) whose outer edge on that side coincides with the inner edge of the container.
- Zeroing the inline-axis margins of a float for the purpose of calculating its intrinsic size contributions or its size in the containerâÂÂs inline axis.
- Trimming the block-end margins of a float to the extent necessary to prevent such a margin from extending the block size of a block formatting context root.

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.
