FWIW I had to revert this some time ago as it broke 3rd PD code: #40192
But would be cool to have CSP strict OOTB at some point

Hi @LadySolveig, how can we help you to get this over the line?

Hi @LadySolveig, how can we help you to get this over the line?

I guess by fixing the conflict and make a PR against @LadySolveig repo :)

Thank you @Bodge-IT for your interest 💚
After the very helpful hint from @dgrammatiko , I thought the PR would probably be better off in 6.0.
I have tested myself whether there is still a problem with sorting or filtering in the frontend. I have not been able to detect any more problems, but I have also included it in the testing instructions.
After the rebase I just waited for your upmerge to solve the remaining conflicts.

The note on the change in manual.joomla.org is still missing - I will deliver it soon and then gladly change the status to ready to review. 😊
