Content Security Policy blocking Rocket Loader and breaking things

I just installed Phabricator and I am unable to use certain features such using certain buttons or selecting tags, etc, looking in the console shows that CSP is blocking a script (rocket loader). I tried to allow it by adding a CSP header with nginx which resulted in 2 csp headers and not solving the problem.
The only way I have found so far to make it work is to (on firefox) disable csp or (on chrome) install and extension to disable csp which isn’t feasible for an entire team to do. What can I do to solve this correctly?

Disable “Rocket Loader”, as the documentation instructs:

Ah, thank you. Not sure how I missed that!
