  [web-animations] keyframes should be recomputed when "bolder" or "lighter" is used on a "font-weight" property
https://bugs.webkit.org/show_bug.cgi?id=251493

Reviewed by Antti Koivisto.

Keyframes can set the "font-weight" property to "bolder" or "lighter". When such values are used, we
recompute keyframes if the inherited "font-weight" value changes while an animation is active.
