Workaround / Solution:
Adding this Part to .htaccess under /fileadmin (Line ~13/14)

<IfModule mod_headers.c>
    <FilesMatch "\.(svgz?)$">
        Header set Content-Security-Policy "default-src 'none'; frame-ancestors 'none'; style-src 'self' 'unsafe-inline'" 
    </FilesMatch>
</IfModule>

Feature request:
can we get an option to change the source of "resources-root-htaccess" which is used in "environment (installtool) -> fix folderstructure"?
