Bug ID: 460388
Summary: Opening then closing widget does not remove created
node from Pipewire, leading to multiple "Plasma PA"
dangling nodes

Platform: Archlinux
OS: Linux

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.
