resizeObserver - refactor how to avoid loop limit errors

[thatblindgeye]

Is this a new component or an extension of an existing one?
resizeObserver helper

Describe the feature
This is a placeholder for discussion/research on how to possible refactor our getResizeObserver method. Currently it uses requestAnimationFrame to avoid loop limit errors from occurring, though when a debounced method is passed in there may still be some visual "flickering" occurring.

One option discussed was updating the proposal made in #7941 so that consumers would opt-in to use requestAnimationFrame, rather than opting out of using it.

Any other information?
