--- Comment #2 from Christoph Bartschat <christoph at 8thwall.com> ---
To provide some additional background, we found that the discrepancy was not related to CSP, but instead the Content-Type header.

It seems like the Content-Type did not affect this before, so there would have been a breaking change since iOS 15.7.


We can see the behavior in the following demo.

For the correct behavior, we should load and see messages from all 3 workers, but on iOS 16.0, we only see one.

We also don't get any indication on why it failed.
