enable-gpu-rasterization with Force Enabled causes graphical blocking on SVGs using CSS mix-blend-mode

Reported by framesp...@gmail.com, Feb 28 2017 
UserAgent: Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/56.0.2924.87 Safari/537.36

Steps to reproduce the problem:
1. Open chrome://flags
2. Set enable-gpu-rasterization to Force Enabled for all layers
3. Create new SVG
4. Set the CSS for an SVG element to use mix-blend-mode:lighten (or similar)

What is the expected behavior?
Expect to see the mix-blend/transfer mode applied correctly, honouring the alpha channel

What went wrong?
The bounding box/alpha channel of the SVG element is fill with black

Did this work before? N/A 

Chrome version: 56.0.2924.87  Channel: stable
OS Version: 10.0
Flash Version: Shockwave Flash 24.0 r0
