Steps to reproduce the problem:
1. Create iframe on a web page
2. Embed animated or interactive svg into iframe
3. Any links on the parent webpage will cause the cursor to flicker in a loop on mouseover after the mouse has entered the iframe

What is the expected behavior?
No cursor flicker

What went wrong?
The cursor flickers over links

Did this work before? Yes Im unsure of the version but there was no problem in 2016 versions of Chrome

Does this work in other browsers? Yes

Chrome version: 64.0.3282.167  Channel: stable
OS Version: OS X 10.13.1
Flash Version: 

Check out a demo illustrating the problem at this link: http://www.revolver.co.uk/test/htmltest/svgtest.html
Notice that there is no cursor flicker over the link on initial page load, however after the cursor has entered the iframe moving the cursor over the link creates the flicker. This only seems to happen with embed svg - video is fine
