Duplicate Queries

When debugging with Query Monitor. I see AST making a huge number of duplicate queries on the orders list page.

Requests like these are made 2-3 times for every row on the Order list page:

$results = $wpdb->get_row( $wpdb->prepare( 'SELECT * FROM %1s WHERE ts_slug = %s', $this->table, $tracking_provider ) );

For one tracking provider, this information can be cached in a global variable. And reused on the same request if the next row also has same provider.
