It is a maddening feature. I often have to stop what I'm doing and constantly click on the done just to be able to see a section of what I'm working on. It does not move out of the way when I attempt to drag it.
I am so sorry that the toolbar is getting in the way during the editing process. To ensure this stops happening for you, try making sure your browser window is at full screen, change your zoom to 100%, or if possible, increase your screens resolution. Another workaround is to break up long blocks of content into a few smaller blocks. I will be sure to notify our developers about this issue thats occuring in your account, but in the meantime- these workarounds should really help!
