Many thanks, this puts me on the path to a solution. I need to change the 
Content-Security-Policy of that server. Is currently for that vhost:

Header always set Content-Security-Policy "default-src 'self'; script-src 
'self'; connect-src 'self'; img-src 'self'; style-src *;base-uri 'self';form-
action 'self';frame-ancestors 'self'"

However the errors I see are that 'self' does not allow setting style-src-attr 
when the source is background: #990099 or margin-bottom: 0cm; line-height: 
100%

Instead of 'self' I tried the name of the server which is shown in the error 
message as https://<server_name>.

Also * instead of 'self' did not work.
