The syntax for stroke-dasharray in the webref/css package does not match the syntax in the specification

[stof]

This package defines the syntax for stroke-dasharray as none | [<length-percentage> | <number>]+#.
The spec at https://drafts.fxtf.org/fill-stroke-3/#propdef-stroke-dasharray defines it as none | <length-percentage>+#.

Full definition of the property in the fill-stroke.json file

see w3c/csswg-drafts#3057 as to why we patched the spec extract

Hmm, looks like there was a resolution in 2018 but the spec still does not reflect it 😢

And support for <number> in browsers is not fully interoperable. Firefox supports numbers as a parser quirks, not as a fully supported type, so it does not work with calc() returning a number: https://bugzilla.mozilla.org/show_bug.cgi?id=1679465

I think both the lack of spec progress and the interoperability risk are worth bringing up in w3c/csswg-drafts#3057 if you'd be so inclined
