Trisquel layout toplevel-id is incorrect

Bug Report Template

dconf watch / is commonly used to monitor changes in GUI elements like the MATE Panel. However, the default bottom panel currently has the toplevel-id "top," which can confuse users interpreting the output.

3. Current Behavior

dconf output for the bottom panel:

/org/mate/panel/objects/object-0/toplevel-id
  'top'

dconf output for the top panel:

/org/mate/panel/objects/object-0/toplevel-id
  'toplevel-0'

---

4. Expected Behavior (optional)

To follow the current approach (also used by Ubuntu MATE)

Expected dconf output for the bottom panel:

/org/mate/panel/objects/object-0/toplevel-id
  'bottom'

Expected dconf output for the top panel remain unchanged:

/org/mate/panel/objects/object-0/toplevel-id
  'toplevel-0'

To add MATE's "New Panel" approach

Expected dconf output for the bottom panel:

/org/mate/panel/objects/object-0/toplevel-id
  'toplevel-0'

Expected dconf output for the top panel:

/org/mate/panel/objects/object-0/toplevel-id
  'toplevel-1'

5. Workaround (optional)

6. Suggestions, Investigation and Possible Causes (optional)

Open /usr/share/mate-panel/layouts/trisquel.layout

In Ubuntu MATE 22.04 the bottom panel is identified as "bottom":

• [Toplevel bottom]
• toplevel-id=bottom

In Trisquel the default bottom panel is currently identified as "top" in /usr/share/mate-panel/layouts/trisquel.layout even though it is located at the bottom:

• [Toplevel top] -- please replace it to [Toplevel bottom] or [toplevel-0]
• toplevel-id=top -- replace it with toplevel-id=bottom or toplevel-id=toplevel-0
