Currently we've got a block in the autosize textarea that depends on requestAnimationFrame, however it won't run if it isn't supported, which means that the fix it's applying won't run on some browsers. These changes add a fallback via setTimeout.

What browsers don't support requestAnimationFrame?

IIRC it’s some of the older IEs and Angular Universal. I did it it primarily for consistency since it’s what we do everywhere we use requestAnimationFrame, but it’s fine if you think that we should close this one.

We should find out if Angular Universal still doesn't support this, I would think it does. And I know IE11+ supports it, so we don't have to worry there

I just tried logging out requestAnimationFrame in the kitchen sink app I got this:

ERROR { ReferenceError: requestAnimationFrame is not defined
