In the attached testcase, I have a <linearGradient> element and I set its "color" CSS property dynamically in a script ran after the DOMContentLoaded fires. The <stop> elements of the <linearGradient> all have their "stop-color" value set to "currentColor" via a CSS rule, and yet that color doesn't change when the parent element's "color" CSS property is updated via script. The testcase works if either of those is true:
1. "color" on <linearGradient> is set statically
2. the <stop> elements have their "stop-color" property set to "currentColor" via the inline "style" attribute instead of a CSS rule.
There was a fix for this issue in Blink lately. pdr, do you know the CL for it still?
This may have been fixed with https://src.chromium.org/viewvc/blink?view=rev&revision=164726?
In general, "git log -S currentColor" is your friend :)
The attached test case renders correctly (gradient to green) on main.
