Why does cameratoolbar Orbit Camera delete my uicontextmenu?

If I follow the following steps, my context menu disappears. Is that supposed to happen?

f = figure;
ax = axes('Parent',f);
cameratoolbar(f,'Show');
c = uicontextmenu();
uimenu('Parent',c','Label','Test');
ax.UIContextMenu = c;
ax.UIContextMenu.Children

Right click on axes

Click on Orbit Camera to toggle on

Right click on axes

Click on Orbit Camera to toggle off

ax.UIContextMenu.Children
