How to disable the croutons overlap over the content?

[RaduCiumag]

I would like to disable the overlap of croutons over the content. Is this an implemented option?

If not, I can do a pull request and change the code, but I cannot seem to find where to do the change.

I was using a frame layout as a viewgroup to display the notification, and that view caused the crouton to overlapped the content.
After the viewgroup was changed to a LinearLayout, no overlap happened.
