Gecko currently doesn't seem to support computed-value time currentcolor for fill and stroke either, so we can probably just follow Gecko's behavior here and use the value from color property here, which shouldn't be too hard I suppose.

Thank you Xidorn.  I am glad that you noticed that this bug is for stylo even though the summary has no 'stylo' at all. :-)

There are so many different color types... Some of them have ToComputedValue in one way, some in the other way... I probably need to understand the situation first...

So this changes it to use color value from the current style rather than the inherited style. This makes sense, but we probably really need a more fundamental fix for currentcolor. I guess this is fine for now as far as it fixes failures.

Thank you Xidorn, I am really glad that you will take care of interpolation for currentColor.
