@nicolas-grekas asked me to to have a look at this after #36678.
If a user has a CSP policy of
default-src 'none', then the WebProfiler copies'none'toscript-srcandstyle-srcthen adds other sources. This creates an invalid policy since'none'is only allowed when it's the only item in the source list.This will probably need to be merged into 3.4 first, I started on 4.4 so I can test in my current symfony project which requires 4.4.
