- There are two html pages on different domains
- the first page has a _blank link to the second page
- open first page, click link to navigate to the second page
- call history.back() on the second page.
- one more time click the link to go to the second page
- now requestAnimationFrame is not working on that page
NOTE: pages should be on different domains. on the same domain Raf works.
