Whenr rendering the SVG image, we use SVGRenderingContext::clipToImageBuffer to apply the mask, but we're not calling cacheNativeImage to send the image buffer to the GPU process, so we get stuck waiting for it when processing the clip-to-image-buffer display list item.
This bug is fixed with by the fix of bug 227519. We are not supposed to draw SVGImage in GPUP.

Oh. I forgot that!
Confirmed bug 227519 disables GPUP rendering of the SVG image. *** This bug has been marked as a duplicate of bug 227519 ***
