[css-sizing] Nobody follows the spec about cyclic percentages in preferred&max sizing properties of replaced element #11452
Description
https://drafts.csswg.org/css-sizing-3/#replaced-percentage-min-contribution
If the box is replaced, a cyclic percentage in the value of any max size property or preferred size property (width/max-width/height/max-height), is resolved against zero when calculating the min-content contribution in the corresponding axis.
For starters, this needs to then floor the max-content contribution by that amount, otherwise the min-content contribution could be larger:
<canvas width="50" height="50" style="width: calc(100px + 0%)"></canvas>- Min-content contribution:
100px + 0px = 100px - Max-content contribution:
50px
But browsers don't have this problem, because they do not resolve percentages against zero. Instead, they treat the min-content contribution as zero:
<!DOCTYPE html>
<div style="width: min-content; border: solid">
<canvas width="50" height="50" style="width: calc(100px + 0%)"></canvas>
</div>This is in fact analogous to #10969
