LGTM1, thank you for addressing this pain point for developers!

The scope of this intent is font-feature-settings, but now that
https://chromium-review.googlesource.com/c/chromium/src/+/6582382 has been
merged, do you want to ship support for font-feature-settings
and font-variation-settings together? I think that would be great, but my
LGTM is not conditional on it.

I also confirmed that the linked tests are failing on stable but passing on
experimental, so everything seems to be in good order!
