Bug Description

using the live image of 22.04, I could see a second icon created in the Mutiny layout Dock/panel. If you click on the trashcan when no other Caja window is open, it creates a new entry in the Dock - as shown in the attached screenshot. Subsequent Caja windows cluster at the new entry.

I have since upgraded from 20.04.4 to 22.04 and can see the same bug.
Mutiny layout with Plank dock shows a second icon for Caja when:
1- click on trash icon in dock (when no other Caja window is open)
2- or, plug in an external drive (again, when no other Caja window is open)

In both situations, a second Caja icon appears at the bottom of the app list in the dock. Subsequent "new window" requests from the Caja menu add to that second icon.
Clicking on the first, pinned Caja icon in the dock opens a new window, again linked to the second icon.
Clicking second icon works as expected, switching to Caja / minimising all Caja windows / bringing them back

screenshot attached of external drive with both Caja icons.

summary: - 22.04 MATE Mutiny dock bug with Caja and trashcan
