Proposed patch for broken CSP

I can confirm that this update fixes the issue on the browsers I've 
tested as well.

Thanks, John for identifying the issue here.
Will be issuing a release update tonight.

Regards,

Sorry for being late to the party.
I can confirm that the proposed patch work w/ 4.3.28 (on Raspbian) and fixes the “cannot use trends-form with Chrome browser”-issue.

Should be applied. JC?

All the best
Thomas

Has anyone found other incorrect CSP headers ?
