IOS clipPath issue

I’m using d3 v4 to render SVG graphics. I’m using a clipPath on a few <path> elements. I have panning behavior on a rect element and the clipPath is helping hide some of the path elements. When panning over in android. The clipPath works as necessary, but when panning in iOS the drawing is rendering funky. See below:

Before Panning

After Panning

Has anyone else experienced similar behavior?
