Picture of dangling Plasma PA nodes in both Helvum and qpwgraph

SUMMARY
Using Pipewire, the Volume Audio widget (Plasma PA) does not remove itself from the graph it seems, but always creates a new node when it is activating. If you were to quickly toggle it over and over, you will end up having many nodes called "Plasma PA" created.
I have not tested Pulseaudio, so I am unsure if it happens there in some way.


STEPS TO REPRODUCE
1. Open some sort of Pipewire graph (Helvum / qpwgraph / pw-viz) to observe. They also show up with `pw-cli list-objects Node`.
2. Open the widget
3. Close the widget

OBSERVED RESULT
    Some nodes get destroyed, but there is one node that doesn't.

EXPECTED RESULT
    The "dangling" node should be destroyed with the others.
