Date range event searches include all events before start date without end date (including disabled events)

This was reproduced on the Demo site (Drupal).

Search Events using a date range.
Be sure to have Events that fall inside, before and after the date range. Make some before disabled.
Perform the search.
All events in the date range are displayed (without and with end dates). But any events before the search start date are also displayed IF they do not have an end date. This includes any that are disabled.
Events after the end date are not displayed whether or not they have an end date.

I will update this issue when I have had a chance to look at the code.
