Lol, how did they even get there, and how did you figure that out? 😀

Oh, I had to revert, because if I remove them, <length> becomes an html element and disappears entirely. Maybe @tabatkins know what the proper fix would be?

Oh, forgot about it. Yep, it must be <<length>> then.

how did you figure that out?

Recently I started a project — csswg-drafts-index. It parses this repo's specs in a JSON dictionary. So I found all propdef and descdef blocks and parsed Value and New value values with CSSTree, which can work with CSS definition syntax. As a result I found some issues, that were addressed with this PR and #4274. Later I grabbed most productions and parsed their syntaxes, and found a couple of problems (not send PRs to address them yet). Current problem syntaxes can be observed in this report (note: by incident, I published a version where issues from #4274 are fixed; however, these fixes are not merged yet)

Super cool project!

I'll make the correct fix eventually, maybe during tpac.

[css-tables-3] Drop zero-width spaces in border-spacing dfn

This addresses the syntax issue raised in w3c#4275 (which got merged then
reverted because `<>` have to be doubled in practice). The goal of the update
is to make the definition compliant with the Value Definition Syntax:
