This seems to be an issue across all of the Sliding Menus including the one on the plugin demo page. It is now clipping the menu where the floating group stops. Meaning if the floating group is 133px tall, the sliding menu is now only 133 px tall. What this does is hide the rest of the menu options.
This creates a navigation issue.
There is also something else that is happening. Please see this loom: https://www.loom.com/share/c531e996b0cb4003bdd014840d0c5d30
This is a pretty important issue for me.
