Some popups like the dupehammer explanation popup or the validation error ones on the contact form do not have the right fonts - the browser has to fall back to a default and quite ugly font instead.
Interestingly, this does not happen for validation popups on posting a question - those remain fine.
Tested with both Firefox and Microsoft Edge.
The dupehammer message was getting attached to the document and not the body of the page - meaning that any styling on the body wasn't being used.
I have updated the script to attach to the body element directly.
With you in the next build.
Just saw that the issue is also on the contact us page - got a fix for that too, but that will go in in the build after next ;)
The JS is appending the HTML of the message between </body> and </html>, causing it to lose part of the styling.
