getAttribute return values incorrectly affected by SMIL animations for some attributes

Reported by bzbar...@mit.edu, Jun 22 2017

Issue description

UserAgent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.12; rv:56.0) Gecko/20100101 Firefox/56.0

Steps to reproduce the problem:
1. Load testcase
2. Look at the resulting alert

What is the expected behavior?
Alert shows "PASS"

What went wrong?
Alert shows "FAIL"

Did this work before? N/A 

Does this work in other browsers? Yes

Chrome version: 61.0.3135.4 (Official Build) dev (64-bit)  Channel: n/a
OS Version: OS X 10.12
Flash Version: Shockwave Flash 26.0 r0

This works fine in Firefox and Safari.

The SMIL spec is pretty clear: https://www.w3.org/TR/2001/REC-smil-animation-20010904/#BasicAnim says:

    When an animation is running, it should not
    actually change the attribute values in the DOM.

Bugs that regressed years ago are not regressions. There is a WebKit roll in that regression range but it does not contain any changes that might cause this, as best as I can tell.

1ea6a232b0d2b355896cb382e53a236d760cc672 is likely what cause the behavior of the TC to change. The behavior as such likely stems from something else though (SVGProperty rewrite?)
