When using exposed filters as pane configuration for a "Content Pane" (from the 'views_content' module in CTools), the "Suggestions depend on other filter fields" feature is ignored (ie. it doesn't take the value of the other filters into account).
The reason is that it puts the exposed filters are under array('exposed' => array(...)) rather than at the top-level.
Detect when we are in a "Content Pane" and move the exposed filters up to the top-level so that views_autocomplete_filters can find them!
Not all content is available!
It's likely this issue predates Contrib.social: some issue and comment data are missing.
As Drupal 7.x and also modules 7.x versions "ended their lives", closing the 7.x issues.
And thanks for participating and using the module.
p.s. if this still an issue on the latest 2.x version, please feel free to re-open and update the version accordingly.
