fix(core): overflow controller resize loop

[zeroedin]

Downstream issue:

❌ > on small screen > reversed right to left language overflow actions > previousTab should be disabled
Error: ResizeObserver loop completed with undelivered notifications. (http://localhost:8003/?wtr-session-id=E_xerQsq1EQq2yny1h-Ga:0)

If you want to prevent these errors, the solution depends on what your intended effect is. If you actually intend to have an infinite loop, you just need to defer the resizing code in your ResizeObserver callback to after the browser repaints. You can put it into a requestAnimationFrame callback.

Documentation Reference

What I did

1. Await browser repaint before triggering overflow side effects

@bennypowers adding await aTimeout(50); allows the pf-tabs tests to complete. That said I'm not convinced that just adding a timeout to the test is the correct way to handle red/green here. Another way to do it is await 3x nextFrame.

beforeEach(nextFrame);
beforeEach(nextFrame);
beforeEach(nextFrame);
beforeEach(updateComplete);

I can almost understand the need for nextFrame better here as we are now adding a tick given the overflow controller implementing the requestAnimationFrame. Thoughts?
