Inline Style doesn't work with Content Security Policy

Created by: michaelbaisch

Hello,

after enabling CSP I get this error in the browser console when opening administrate:

Refused to apply a stylesheet because its hash, its nonce, or 'unsafe-inline' does not appear in the style-src directive of the Content Security Policy.

Referencing this line:

<svg xmlns="http://www.w3.org/2000/svg" style="display: none;">

Maybe this simple style could be transferred to the administrate css?

Greetings, Michael
