Toggle Mode Slide Over Content Not Working

Hello, I am using a scroll container on a page layout that uses the left region as a toggleable navigation menu.  It works normally when I use the "Shrink" or "Push aside" toggle mode options, but when I choose, "Slide over content", it puts it permanently behind the page objects.  Any ideas what I am doing wrong?

Don’t think you are doing anything wrong, this option seems to be broken for some time now.

Would be helpful to raise a support ticket for this with Mendix support.
