Regions do not respect the order on Layout designer

Hello.

In the new version 1.8.1 when creating a new region in the layout designer it appears in the position more in the background and not in front of everything, , which is how it should be

As you can see in the image, the new region is the one that is located completely below the other and therefore the menu can not be accessed.

It would be possible indicate a possible solution.
Thank you so much.

(Sorry for bad english)

We have it logged here and there will be improvements in that matter in the next release (1.8.2).
