CiviEvent menu listing showing old events
CiviCRM 5.1.2 on Joomla 3.8.10.
Problem as reported: Trying to create a menu item for an event info page, and the drop-down in the Joomla menu manager is only displaying past events. The drop-down for the Event Registration Page shows the currently active and upcoming events - there are only 2 of them.
Investigation: the selector for showing events filters by 'active' and shows at most 100 events, but it does not filter by date - so when there are more than 100 events, new ones are not shown.
