Submenus not displayed

[quequotion]

Submenus in ayatana indicators are not displaying in wingpanel.

For an example, try indicator-powersave.

The indicators appear in the panel, and can be used, but submenus are empty.

These menus work fine in lxpanel and older versions of wingpanel/wingpanel-indicator-ayatana (like those available in elementary's PPAs)

Submenus are also missing from glippy-indicator.

Revision testing indicates commit 105c1d0 in wingpanel broke submenus in indicators.

This is not a bug in wingpanel-indicator-ayatana, although I'm not entirely certain it should not be fixed there, as I don't know of any native indicators that have submenus to test if they are working.

Another way around this would be to make changes to the indicators themselves, as was done with the native wingpanel indicators, but they are quite dissimilar. Indicator-cpufreq/powersave is written in python, while glippy is written in c#. I've tried to find documentation on both, but so far nothing useful--I am not sure if there is any equivalent to the "visible" property used in vala.

It doesn't seem like that should be necessary however, as only submenus are affected; other menu items appear and function normally in these indicators (except for radio button dots).
