Adjusting volume displays a notification bubble for every instance of the volume plugin

[Alistair Buxton]

To reproduce:

1. Add more than one xfce4-pulseaudio-plugin to the panel. (For example, because you have a panel on more than one monitors and a plugin on every panel.)
2. Adjust the volume.

Result:

You get a bubble for every instance of the plugin. If you have three plugins, the volume notification will be displayed three times.

See screenshot.

Just to add some context: all the bubbles appear stacked on the same monitor. (Last time I checked anyway.)

They should either be one per monitor or preferably just one on the current monitor. I'm not sure if the former is possible as the notifications seem to follow the mouse pointer.

This affects me on an upgraded 22.04. I have no multiple panels, or multiple Pulseaudio plugins on my panel.
