Fix the background color animation between color spaces. srgb and oklch are not behaving correctly.

This CL fixes when `background-color` and the one in keyframes is
`no-legacy` and `legacy` color space mixed, they will end-up been
interpolate as oklab with sRGBLegacy.

In particular `oklch(45% 0.2 264)` is treated as non-legacy so has been
converted into `oklab(45% -0.02 -0.2)`, but the original
`background-color` is in hex format, will keep as is(sRGBLegacy), and
These two colors are blending with sRGBLegacy mode; that is why we only
see r component is changing, the other two components are always 0 in
devtools, because they are mixing togather with different expectations.
One want to interpolate with oklab but the other want to interpolate
with sRGB.
