PanelMenu: Menu items with no sub-items toggling border radius

[XanEliot]

Describe the bug

In our program we are using PanelMenu for a side bar navigation component. We require some items to have sub-items but most are standalone. I would expect the border radius of the standalone items to remain the same, but the bottom radius becomes 0 as if the item were expanding.

An example within the PanelMenu documentation:
https://primevue.org/panelmenu/#command
You can see the behavior by clicking on the "Sign Out" button multiple times. Every time it is clicked the bottom border toggles.
