       Edge: Not Tested

What steps will reproduce the problem?
(1) Within a <g> element, create an svg shape element such as <rect> with a set stroke-width, and the property "vector-effect" "non-scaling-stroke".
(2) Set or adjust the transform scale value on the g element
(3) Observe that the stroke size does scale when it should not.


What is the expected result?
The stroke should remain at the size initially specified on the element rather than scaling with the transform.


What happens instead?
The stroke scales with the transform.
