Description Daniel Holbert 2021-01-29 16:13:25 PST
(1) Load this testcase:
or this equivalent data URI:
data:text/html,<table border style="width:max-content"><td style="width:100%25">hi</td><td style="width:100%25">hi</td>

No infinitely-sized content.

The first table cell ends up infinitely-sized (or at least absurdly large).

Chrome gives ACTUAL RESULTS as well -- I suspect this is an issue that predates the blink/webkit fork. I filed https://bugs.chromium.org/p/chromium/issues/detail?id=1172498 to track this in Chrome.

Firefox gives EXPECTED RESULTS -- it just renders both cells as being content-sized.

I am not too fond of the term "keyword" but I don't have a better candidate (unless we start renaming more functions here, but I don't think it's worth it)

The spec term for these keywords in css-sizing-3 is "auto box size" keywords, so an alternative could be "computeAutoBoxLogicalWidths", but as you say there'd be a bunch of other renaming you'd want to do to stop using "intrinsic".
