What package is this feature request for?
rrweb
Problem Description
We noticed that when using rrweb with Angular (which uses Zone.js under the hood), you'd often run into major performance problems. A user has probably tracked down the issue, which is that angular patches requestAnimationFrame for change detection, and since rrweb uses that quite a lot this may lead to performance issues.
Proposed Solution
I implemented a tentative fix for this here: getsentry#150
Which is to pull requestAnimationFrame from an iframe to get a "fresh" instance. Would you be interested to also have this in the mainline rrweb? If so, I'd happily port this over here as well.
Alternatives Considered
Leave it as is, it's not technically a bug.
