Patch

This patch is expected not to build until the patch for bug 233868 lands but can already be reviewed.

[Antoine Quint]

I filed https://github.com/w3c/csswg-drafts/issues/6861 to propose to revive the discussion of custom effects in Web Animations.

We don't have a type for duration?

This might be nicer as a function that returns the variant directly into customEffectOptions.

Will fix Windows failures in https://bugs.webkit.org/show_bug.cgi?id=233887.
