Manual test

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

Added in r273656, it&apos;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:

&gt; 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 &quot;transform&quot; 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.</thetext>
