My teammate and I were accessing some video resources in a LMS which were put up in the Vimeo's video player.
I found that the *Play* button, *Captions* menu and the *Video quality* menu were un-labelled, I could verify that from the elements list as well.
However my teammate has all those buttons labelled on the same page. We both use NVDA 2021.1, I am on Chrome 92 and she is on Chrome 91, that's the only difference.
I am not sure if this question qualifies to be on this list or not, but any idea why this is happening?
