The element losing its focus box has been since 1.3.2 (containers are fine, but elements do not show).
This was the response back in July last year via email:
- Element UI box
Sorry I mean the green focus border for elements. The orange, blue and (red/purple) border colours show when you select that container and remains in place, whist you are editing - However when you click on an element like heading, text, the green focus box comes up but disappears if you move to the editing panel. It does not stay active.
- Noted. We confirm it and it will be fixed soon.
