I can reproduce the problem on my iPhoneX iOS 15 + Safari.

Unrecognized Content-Security-Policy directive 'worker-src' console error shows up when attempting to spawn a text bubble.

I am now able to reproduce this issue 100% of the time on Safari 15.2.

Can anyone test on Safari 15.5 or newer? Safari seems to support worker-src from 15.5. https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Security-Policy/worker-src#browser_compatibility
