Rather than using rAF, you probably want testRunner.layoutAndPaintAsyncThen()

[lushnikov, 2016/07/27 03:14:46]

I'm not sure if the layoutAndPaintAsyncThen will force raf; but afaiu rAF's are
synchronized inside the process (so requesting raf is good enough)

Please don't. See invokeInPageAsync:

Beautiful. Thank you!
