Move off the editing area the warning 'This post has been updated elsewhere...'

In the post editor, please move off the text editing area this occasional warning:

This post has been updated elsewhere since you last published! Delete draft and reload.

The warning is currently displayed at the bottom of the editing area and covers a few lines of text making it nearly impossible to access or change the text, typically the final paragraph or the last few lines of a post.

Intead, please move the warning anywhere else it doesn’t cover the text at all, make it dismissable, or at least let me move it elsewhere.

As for the warning itself, it’s confusing. I’m positive I haven’t updated the post elsewhere when the warning shows up. I use only a single browser tab on a single device to visit the editor page. If the system knows where else the post was updated, I’d appcreciate a link or some indication of where.
