block moving is completely broken

No matter what function I use, no matter how I click it, when I try to move this text box, for some reason it tries grabbing the entire screen. I basically cannot edit the site because of this problem.

Edit: Okay I got it to move but it still feels like a bug because I have to click drag, then let go and click drag *again* before the editor box opens and allows me to move the block. I mean it works but it feels really jank.

Another Edit: Nevermind, doing that only works sometimes, it's definitely bugged.
