In Vision 8.0.15 if you bind a property on a group to a property on another component then ungroup that group you will then not be able to delete the other component.
Repeatable with the visibility property on a group bound to the Selected property of a toggle button. After ungrouping the group attempts to delete the toggle button give error “Cannot Delete. Cannot get path for floating component: Group”. No workaround found which allows the toggle button to be deleted (recreating the group does not work)
