ios 14 and macOS safari 14 broke captions using video.js

The error message from the console:

[Error] Unsafe attempt to load URL from origin . Domains, protocols and ports must match.

My VTT domain is different than my origin domain.

It seems iOS 14 and macOS Safari 14 are more strict than prior versions. I was able to fix the problem by adding a crossorigin like so:

    <video
      :id="videoIdentifier"
      crossorigin="anonymous"
    />
