helged opened a new issue #1758: ModPagespeedHonorCsp ignores that unsafe-eval 
is not an allowed script source
URL: https://github.com/apache/incubator-pagespeed-mod/issues/1758
   I just upgraded to mod_pagespeed I hoped that I could finally get 
rid of `script-src 'unsafe-eval'` in my content security policy. So I added 
`ModPagespeedHonorCsp on` to my configuration. After removing `unsafe-eval` 
from the CSP, restarting Apache, and, for good measure, deleting pagespeed's 
disk cache, Chrome's dev tools console shows errors like the following:
   _Uncaught EvalError: Refused to evaluate a string as JavaScript because 
'unsafe-eval' is not an allowed source of script in the following Content 
Security Policy directive: "script-src 'unsafe-inline' https: data:"._
   Comparing the count of evals before and after the change, it turns out that 
not a single eval has been removed my mod_pagespeed. I am referring to 
constructs like the following:
   One of the sites running on the server is 
[uberagent.com](https://uberagent.com) in case you want to take a look. I 
reverted the change, of course.
   The configuration shown at `/pagespeed_admin/config` is as shown below.
