Hidden SVG element and animation bugs.

Reported by hetdoetj...@gmail.com, Oct 12 2017 
UserAgent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/61.0.3163.100 Safari/537.36

Steps to reproduce the problem:
1. Create an SVG that with a path inside a <def> tag
2. Create another SVG that references the first one
3. Apply a CSS animation that animates the stroke-dashoffset
4.1. When applying 'visibility: hidden' to the first SVG, you can still see the animation playing there.
4.2. When applying 'display: none' to the fist SVG, the second animation won't play in the referenced SVG. 

What is the expected behavior?
For 4.1. the animation shouldn't be visible.
For 4.2. the animation in the second SVG should still be playing.

What went wrong?
Both of the expected behaviors aren't happening.

Did this work before? N/A 

Does this work in other browsers? Yes

Chrome version: 61.0.3163.100  Channel: stable
OS Version: 10.0
Flash Version: 

In the reduced test case, only the SVGs in the corners should be playing.

This is probably two bugs:

  * 'visibility: hidden' things being painted and
  * animations not running/applying on 'display: none' subtree

the latter is most likely a generic CSS animation issue (since animations are applied during style recalc and require layout objects to work.)

Right, 4.2 is a dupe of our other referencing display: none bugs.

The visibility: hidden still painting is an odd one though.
