Dashboard panels intermittently disappear when they are in the 'default' panel group.

[Travis Tripp]

In a panel enabled.py file you can make a panel appear directly in the dashboard nav menu by putting it in the default panel group:

# The slug of the panel group the PANEL is associated with.
# If you want the panel to show up without a panel group,
# use the panel group "default".

At some point in Ocata, something changed that made panels intermittently disappear from the nav menu if they are not in a panel group and you are using the 'default' theme. If you switch to the material theme, this does not occur.

For example, with searchlight ui enabled [0]

The search panel will appear in the nave menu when you first open the project dashboard. However, if you then expand the compute panel group and click into Instances, Volumes, etc, when the page reloads and displays one of those panel, the search panel (which is in the default panel group [1]) will no longer appear in the left hand menu nav.

Confirmed. The HTML is there but hidden from the user because of the .collapse class.
