Preview iframe is empty

[rami-res-zz]

Thanks for your extention! Really good one.
But recently I always get an empty preview.
I use Google Chrome Version 75.0.3770.100 (Official Build) (64-bit)

And in the console have also the error:
fused to display 'https://stackoverflow.com/questions/.../...?rq=1' in a frame because an ancestor violates the following Content Security Policy directive: "frame-ancestors 'self'".

It seems stackoverflow blocked another domain iframe according to Content Security Policy

Just F.Y.I. @techsin I've added a variant https://github.com/wayou/SoRatings and may fixed the issue.
