can not exit split view
I am using two Chrome browser windows in Split View, but I can't get them to close. Moving the mouse to the top of the screen does not bring up the 3 window buttons. I can swipe left/right to other workspaces, but if I try to open Chrome, it just takes me back to the space with the two split windows.
