Test case

Strokes with the style {vector-effect: non-scaling-stroke} are scaled when transforming an SVG by setting an otherwise-unspecified viewBox via animation.

Tested on Windows 7 @ Chrome stable, Windows 8 @ Chrome dev, Arch Linux @ Chromium 26.0.1410.63, and Android 4.2.1 @ Chrome latest.

See attached test case.

In writing this test case, I found that the "Desired behavior" (employing a workaround by setting the viewBox attribute to the end result) produces artifacts when animating on Windows and Linux. This is not part of the desired behavior, and I will file a bug summarily.
