Same like in bug 48215.
Does this only apply to elements with local transform in combination of animateMotion, what about animateTransform? If you need animation tests, you should use the animation test api in svg/animations. Please take a look there. Using setTimeout is definitely wrong.
If it does not only effect animateMotion, I'd like to see more tests.

[Shane Stephens]

This bug does not affect animateTransform as animateTransform appends or replaces the target element's transformList directly, whereas animateMotion acts via the m_supplementalTransform member of SVGStyledTransformableElements.

Excellent job. I guess you're fixing operator* afterwards?

[Shane Stephens]

Yep, I'm tracking that in 48031

The layout test was failing on the commit queue because run-webkit-tests (which the commit queue uses) is less permissive about newlines at the end of the expectations file than new-run-webkit-tests (which I was using) is.  That problem is fixed in the latest patch.

[Shane Stephens]

tony: patch is identical to the previous r+'d one except for an extra newline at the end of the test expectations, and slightly looser tolerances for the location of the object at the start and end of the animation.
