How to disconnect the field on the new GhostText?

Yeah the current disconnection logic isn't super clear. In the previous version you would just click the button again and it would disconnect, but now it just looks for more fields.

So the solution I came up with is to right click the button 😬 or to just close the editor tab (which would make more sense, since _you're done with it so you want to go back to the browser_)

Does anyone have any suggestions for an intuitive way to disconnect the editor from the browser?
