Fixed rAF throttling issue caused by new Chrome flag#39

Chrome's new "Throttle non-visible cross-origin iframes" flag causes problems for code running inside of hidden iframes. In this case, animation frames get scheduled without any error but never get called. This causes problems for the React DevTools browser extension specifically. This commit adds a workaround by scheduling a backup timeout along with animation frames. In the normal case, these timeout will be cancelled by the animation frame (which will run first).

not sure if using Flow/TS, but is there any scenario where the window object would still be null here?

No. The else here falls back to global when window and self are undefined. One of the three should always be present.

also assuming there’s no possibility that one of the raf/cancel functions are not null without the other also not being null, right?

If either request or cancel function is null, we'll hit the above timeout based code path.
