webanimations/transform-transition-with-delay-on-forced-layer-with-transform.html

Added in r273656, it's flaky showing the actual image to be already scaled down. Likely missing to implement the same fix in the texmap animations? From the revision comments:

> Prior to this patch, this test failed because, while in the delay phase, the transition would mean the underlying transform was applied twice: once by the non-interpolating animation generated for the underlying "transform" value, and once by the first keyframe of the transition since it fills backwards.

Manually testing with both Epiphany 2.30.5 and MiniBrowser ToT, the old behavior is still present.

Attached is a manual test based on the original layout test, with a shorter delay.
