PanelMenu: Submenu's not using animations

[SimonJ-DR]

Describe the bug

Opening one of the top level items displays submenu's for a brief moment then collapses them. After that they cannot be opened again. EDIT: This issue seems to be fixed. Although there is still some funky behavior going on. When multiple layers are expanded, opening a new submenu it'll close on layer without animations.
