[css-sizing-4] How to parse "contain-intrinsic-size: 10px auto 20px;" #6391
Description
https://www.w3.org/TR/css-sizing-4/#intrinsic-size-override
The grammar allows the length and auto in any order. Therefore, the following is valid:
contain-intrinsic-size: 10px auto 20px;
However, should it be interpreted as contain-intrinsic-width: auto 10px; contain-intrinsic-height: 20px; or as contain-intrinsic-width: 10px; contain-intrinsic-height: auto 20px;?

Following up: we just fixed the ordering as
auto <length>, since that reflects the importance of the values and solves the parsing issue -10px auto 20pxis thusc-i-width: 10px; c-i-height: auto 20px;.Loirooriol commentedon Sep 8, 2021
<length> | auto <length>could be shortened toauto? <length>tabatkins commentedon Sep 8, 2021
It can be, yes, but we sometimes separate out clauses like this when the behavior is significantly different and we want to talk about the cases separately.

Thanks, sgtm. I implemented that in https://chromium-review.googlesource.com/c/chromium/src/+/3138514.
