expanded menu items not visible in mega menu [#2541548]

I would like to report a strange issue with taxonomy menu generated menu items that have child nodes.
These parent nodes don't seem to show up in my frontend as they are not generated to UL>LI html structures.

To describe the scenario where it goes wrong and also how it can be fixed (only) manually afterwards has been recorded in my attached screencast.

Somehow the way the menu items are saved by taxonomy menu is not identical to the way regular menu structure admin does. Anyone a clue what the cause might be ?

After diving into the menu_links database, i noticed a slight difference between taxonomy generated (customized) menu links and manually generated/updated menu links.
See attached screenshots.
Apparently my mega menu is not allowing expanded links that have the 'customized' flag set to 1.

This issue is therefore not longer related to the taxonomy menu module.
Will be closed after investigation and fix of the mega menu implementation...
