[css-text-decor] text-decoration-width claims to be a sub-property of text-decoration, but text-decoration disagrees.

https://drafts.csswg.org/css-text-decor-4/#text-decoration-width-property says (emphasis mine):

This property, which is also a sub-property of the text-decoration shorthand, sets the stroke thickness of underlines, overlines, and line-throughs.

However that links to https://drafts.csswg.org/css-text-decor-3/#propdef-text-decoration, which makes no mention of this property.

How does the text-decoration shorthand impact this? Does it reset text-decoration-width to auto? Or does it actually allow parsing text-decoration-width?

Looks like the definitions from L3 generally haven't been imported to L4. The answer should be, "text-decoration is able to parse it in", so

text-decoration:  | | <'text-decoration-line'> || <'text-decoration-style'> || <'text-decoration-color'>

becomes

text-decoration:  | | <'text-decoration-line'> || <'text-decoration-style'> || <'text-decoration-color'>|| <'text-decoration-thickness'>

<dael> github: https://github.com//issues/3993
<dael> astearns: emilio added this and fantasai commented.
<dael> astearns: Anything we need to do?
<dael> fantasai: Not unless someone disagrees with making it a sub property
<bradk>  🌎 📆
<dael> astearns: I have not read through the text. Is there a spec change?
<emilio> astearns: I'm fine with fantasai's comment, updating the spec would be nice
<dael> fantasai: Hang up is text-decor L3 text isn't folded into L4. I need to cross check before I copy over and merge in. L4 is basically a diff spec atm
<dael> astearns: So we'll close this as soon as you cross check and poss. update spec
<dael> fantasai: Yeah
<dael> astearns: Any disagreement with that course of action?
<dael> ??: nope
<dael> astearns: Let's leave it at that.

Note that this property is now named text-decoration-thickness (not -width) in the ED.
