@ghys, I did submit a PR to address the formatting issues, but I could not reproduce the blank pages coming up.

I did notice there were console warnings related to #3918 whenever the popup opened - I have fixed those in PR #3997. I doubt those address your issue, but it would be worth checking out that PR to test.
