SVG infinite animation lead to memory increase and high CPU utilization

Reported by shelbeni...@gmail.com, Aug 31 2016 
UserAgent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/52.0.2743.116 Safari/537.36

Steps to reproduce the problem:
1.  open this demo: https://jsfiddle.net/m5up9fpo/4/
2.  open task manager
3.  see memory and cup utilization, it may need some time to see the change

What is the expected behavior?
memory should be stable, no increase

What went wrong?
memory increase in both windows and mac OS, high CPU utilization on Mac

Did this work before? N/A

Able to repro this issue on MAC (10.11.6) for Google Chrome Stable Version - 52.0.2743.116

This is a Non-Regression issue existing from M45 - # 45.0.2454.0

Before this build, there is no animation in the JSFiddle provided.

Investigating on Ubuntu with v54.0.2840.6.

Heap profiling (https://chromium.googlesource.com/chromium/src/+/master/components/tracing/docs/heap_profiler.md) is showing a large amount of memory going into:

FrameView::performLayout
VisibleUnits::mostBackwardCaretPosition
EditingUtility::previousVisuallyDistinctCandidateAlgorithm
VisibleUnits::mostForwardCaretPosition
VisibleUnits::mostForwardCaretPosition
startWordBoundary

Passing over to the layout team for further triage.

If someone has time, could they re-verify this?

I've had the TC running during the day, and the memory usage has been growing slowly (~4k/second or so based on the Task Manager readings.)
