Steps to reproduce the problem:
Open the attached path-bbox.svg file. The arc is drawn using a path element. The path is a child of a g element. The blue dashed rectangle is computed in script and shows the bounding box of the path element. The red rectangle is also computed in script and shows the bounding box of the path's parent g element. 

What is the expected behavior?
The bounding box of the path should tightly enclose the arc. The bounding box of the g element should tightly enclose the arc.

What went wrong?
The rectangle returned by getBBox is much larger than the arc. This is true for both the path and the path's parent g element. 

Did this work before? No 

Chrome version: 53.0.2785.101  Channel: stable
OS Version: 8.1
Flash Version: Shockwave Flash 22.0 r0

Chrome 55.0.2859.0 canary gets the path's bounding box right but the g element's bounding box is still wrong.
The bug is not exhibited by Firefox or IE11.
