The RSS Publisher only works properly with one feed:

Steps:
1 Add a RSS Publisher, the one that come with NYT by default
2 Configure it to use a second feed, along with the NYT
3 Verify if both feeds load properly when the page loads
2 Try to collapse news from the second feed, this action will hide news from the first feed as if you had clicked on it.
