Search auto-complete on api.drupal.org sometimes doesn't work

Migrated issue

Reported by: jhodgdon

If you go to api.drupal.org (home page) and start typing in the search box, you don't get the auto-complete list showing up (or at least I don't).

If you click on a link or otherwise navigate to any other page, you get the auto-complete list showing up when you start typing in the search box (or at least I do).

Not sure why....
