What I expected to happen was...:
I should have been able to click on the realm and join

What actually happened was...:
when I clicked on the realm to join it pulled up the buy a realm popup.

Steps to Reproduce:
the way I got around it was fullscreening then making the tab smaller till I could see the text that said want to buy a realm. I then clicked on the text, closed out of it and the play button was highlighted
