Reproduced on iPad Pro 2015

To reproduce bug:
- restart Safari
- navigate to the bugzilla page bug 231031
- open the link (for rgba test case)

-> observe consistent sub-60fps reports on most loads

To reproduce working scenario
- copy the rgba test case to clipboard
- restart Safari
- paste the link directly to safari

-> observe consistent 60fps reports

So the buggy behaviour needs some other page to be loaded before. It is unclear which page features trigger the problem.

The buggy vs non-buggy cases have similar looking CPU traces.
