Test case

See https://code.google.com/p/chromium/issues/detail?id=569703
which is talking about whether 0 should be handled as 0deg.

However, it's even worse. See the examples in the attached file, where
linear-gradient(95deg, red, blue) is ok
but
linear-gradient(95, red, blue) is parsed with 3 colours.

smfr says there are also differences in quirks v standards mode

Implementing https://quirks.spec.whatwg.org/#the-hashless-hex-color-quirk per spec would maybe fix this.

cdumez, want to take a stab at this? :-)

Chromium passes the tests

There is no difference in attached test case across all other browsers (Chrome Canary 108, Firefox Nightly 107 and Safari Technology Preview 154).

First two square / rectangular has gradient from top to bottom starting from bad and third square / rectangular from the right side to left with same pattern.

Is something further required? Thanks!

Let's say "no", as identical rendering is interoperable. Someone can file a follow-up bug if needed.
