[css-sizing-3] Content contribution of min-inline-size:fit-content and max-inline-size:fit-content #10721
Description
We came across this from a bug report submitted to us, and basically it comes down to these cases:
<!DOCTYPE html>
<div style="width: fit-content; border: solid 10px;">
<div style="max-width: fit-content; width: 100000px;">
abc def ehg
</div>
</div>

<!DOCTYPE html>
<div style="width: fit-content; border: solid 10px;">
<div style="min-width: fit-content; width: 10px;">
abc def ehg
</div>
</div>

Basically:
- For Blink - The available-size is indefinite (during the content contribution calculation) so we'll throw away the
fit-content, and just treat themin-inline-size, andmax-inline-sizeas 0, and Infinity respectively. - For Gecko - The available-size is indefinite; for the
min-inline-size-fit-contentbecomesmin-content, and formax-inline-size-fit-contentbecomesmax-content.
Gecko's behaviour here is reasonable (at least to me), but isn't in the spec (from my reading).
