I finally recorded a video of this UI problem.
- Both these text elements are the same component.
- The element lower down shows the pop-out arrow for the editor
- The one at the top has now arrow, as the image within the content seems to obscure it
- These are both 6.x components, the same thing, but one with an image and the lower down one without

The only way to get back into the top element is to keep removing content (such as the image), clicking elsewhere, and then coming back.
Bill (no arrow).
