Everything seems to fail because the expected value is somehow "corrupt", i.e in all cases we see:

...assert_equals: expected "70 " but got <actual value, generally correct>

and 'expectation.is' is also included in the output and appears OK (and matching in all cases I checked.) Could be a harness (interpolation-test.js) error, or a maybe some sort of RegExp caching error (given that the value gets passed through several RegExps and are somehow always end up as "70 ".)

This is SVG related, not main-thread animation related.

Web Animations: Shard startOffset tests

The SVG interpolation and composition tests have taken
up to 9 seconds to run.

We shard them to reduce timeouts.
