[csswg-drafts] [css-animations-2][scroll-animations-1] Avoid including properties that should be interpolated at boundaries when adding neutral keyframes (#8491)

kevers-google has just created a new issue for https://github.com/w3c/csswg-drafts:

== [css-animations-2][scroll-animations-1]  Avoid including properties that should be interpolated at boundaries when adding neutral keyframes ==
Steps 7 and 8 in https://drafts.csswg.org/css-animations-2/#keyframes outline the procedure for adding initial and final keyframes for properties that are missing at the boundaries.  This procedure should be updated such that properties that are missing at 0 or 1, but which should be interpolated at the boundary are not included.

The set of "from" properties should include all properties found in a keyframe with offset <= 0.
Conversely, the set of "to" properties should include all properties found in a keyframe with offset >= 0. 

Keyframes with a timeline offsets can result in computed offsets being outside the 0 to 1 range and should be interpolated at the boundary (see https://github.com/w3c/csswg-drafts/issues/7825).
