Safari pop-outs not loading

Is anyone else experiencing an issue with pop-out windows on safari? Whenever I click the button, the window simply remains blank. This started randomly. Hard to tell when exactly, maybe a month or two or ago.

Well, Safari is not one of the officially supported browsers for Roll20, but if you don't want to (or can't) use chrome/firefox, then I'd suggest making sure you don't have any extensions installed that are causing the issue (not even sure Safari has these). 

Safari does have extensions, but more importantly, it has a setting to forbid pop-ups. I'd suggest toggling that first.

I don't have any extensions for it and disabled the popup blocker. I am aware I can use Chrome without issue, I just normally use safari and this just randomly started. No setting changes.
