Hi Kevin,
You are right, I think I may know what it is now. So the stylesheet gets corrupted whenever it gets to the title font rule. I guess it’s because probably of the escaped apostrophe characters. The minifier might not be able to handle that.
Anyways, I have sorted that by changing the result title link font option to inherit: https://i.imgur.com/w31np21.png
Now both instances should start come out correctly. I will investigate this further on my local environment, and if possible then remove the apostrophe escape characters in the future release, so the minifier can handle them better.
