What?

Close #48067.

Why?

Fix the flakiness of the a11y test.

How?

Playwright runs too fast before the modal can run some of the code for constrained tabbing. We explicitly wait for aria-label to be sure that tabindex has been updated. I'm not sure why it's only failing on Webkit though. This is not an ideal solution but I couldn't figure out a better one at the time. Let's merge this first to unblock other PRs, we can figure out a better solution in another PR.

I ran this locally 100 times and they all passed.

Testing Instructions

CI should pass.

Staring at the e2e tests spinning icon to see if they pass 🙀

Okay, this seems to work now. I use a different approach by asserting the aria-label. This is not an ideal solution but at least it can unblock other PRs.

@kevin940726 good finding! So, to my understanding, it was a timing issue?
In that case, if possible, I'd suggest to assert for the tabindex attribute rather than the aria-label, as tabindex is the attribute responsible for making the scrollable element focuable.
Yes, tabindex and aria-label are set at the same time, but just in case... 🙏
