Google has come through and has now stopped deduplicating the featured snippets that show up on the right side. That is until Google moves the right side featured snippets to the top left position. Google said they would do this temporarily until Google does move those featured snippets.
Here is a screen shot, click on it to enlarge:
Previously, with the deduplication of featured snippets, you would not see the ipostal1.com URL on the left side like that. And you won't see that if the featured snippet was at the top, you are only now seeing this because the featured snippet is on the right side of the page.
This went live super early this morning, maybe around 2am ET. Heba Said posted around 2am about this:
Google fixed the side featured snippet (or knowledge panel) and they added them on position #1 as well. @googlewmc pic.twitter.com/B1TaNIKldi

Looks like G has rolled back this change now: https://t.co/VyOOlWilDM. Previously were burying that 2nd URL for those FS/KP type features that sit on the right on desktop. Should see CTR for those queries increase a lot now. https://t.co/cdqeGw33kK

Again, this should be how things are until Google moves the right side snippets to the left position.
