It looks like we currently don't respect SVG's color-interpolation attribute, https://svgwg.org/svg2-draft/painting.html#ColorInterpolation, for SVG gradients. Now that we can easily support linearSRGB interpolation, this should be easy to add.

Firefox shipped this in version 123 [1], and I'm looking at getting this out the door in Chromium/Blink, so consider this a nudge to get the above patch out the door ;-). [1] https://www.mozilla.org/en-US/firefox/123.0/releasenotes/

SeeAlso Bug 305066 and the associated PR. // FIXME: When we support `color-interpolation` (webkit.org/b/234783) it would be OK to convert the colors to linearRGB when interpolation is linear. https://github.com/WebKit/WebKit/pull/56730/changes#diff-d84885f211289ef03c36e79f71f6030345bfeb98029768e656aa326dc4cc178dR53
