AR: The outer box is not colored in Nightly
ER: Maybe?

Tentatively putting in Layout, but please reclassify as needed.

Could repro on a build from Jan2022, so not a new regression.

bug 1885716 is about the same demo but the issue is different (color rendering)

Either WR or web painting seem more likely components for this :)

yeah, i was thinking it could possibly be due to the pseudo:class thing written in the comment.. But who among us truly know how the web works.

        Reduced test-case. (obsolete)

It seems the gradient is not working at all, maybe we assume that a single stop causes the gradient to be solid, which is usually true, but not if the color interpolation is not srgb?



    
    

    
  
Yeah, if I specify two stops like:   background-image: linear-gradient(in hsl longer hue 45deg, #f66 0 0, #f66);, then it works as expected...



    
    

    
  
Yeah, so this check isn't quite correct, since the end stop might be implied from the start, Ashley can you take a look when you have the time?

Did you mean to make this reduced testcase for bug 1885716?

(I had filed this bug specifically for the the outer square not having any color at all, which seems to be broken atleast since 2022. Prior to that, the square would be colored, but different from Chrome)



    
    

    
  
Ah, sure, sorry for the mix-up.
