Issue

The Virtual Machine Tab in the Cockpit interface show the error message:

Refused to load the font 'data:application/font-woff;base64,d09GRgABAAAAAF9QAAsAAAAAXwQAAwAAAAAAAAAAA…BiAHkAIABJAGMAbwBNAG8AbwBuAC4AAwAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA==' because it violates the following Content Security Policy directive: "default-src 'self' 'unsafe-inline' 'unsafe-eval'". Note that 'font-src' was not explicitly set, so 'default-src' is used as a fallback.
