Comment:

 To reproduce the issue (and test a solution) when there is no duplicates
 in the last 3 posts from planet.wordpress.org, you can have it display
 more than 3 by editing line 1348.
 https://core.trac.wordpress.org/browser/tags/4.8.2/src/wp-
 admin/includes/dashboard.php#L1348.

 The output of this widget is cached, so one may also need to skip the
 cached output by commenting out lines 983 to 988 for testing.
 https://core.trac.wordpress.org/browser/tags/4.8.2/src/wp-
 admin/includes/dashboard.php#L983

 The patch above replaces `wp_widget_rss_output()` with its own source code
 as suggested by @birgire , modified to detect and skip duplicate entries.

 (This is my very first patch so please bear with me and let me know if I'm
 doing anything wrong :) )
