I checked this on a local test site and didn't see any problems with using the Front-end Layouts Editor, I was able to hover over each of the areas of my content which showed the edit links which I was able to use to edit the cells.
Is there a specific Layout you are using where you can see this problem. Can you point me to an example post where it is not working?
