When documents fetched to see on UI, one extra document is fetched

Build 5.0.0-3509
Observed that when Documents button clicked to see documents call made from browser is- http://<IP>:8091/pools/default/buckets/travel-sample/docs?include_docs=true&limit=11&skip=0 where limit is 11. This fetches 11 documents and 10 are shown on UI default. If clicked on next set of documents, skip becomes 10 and limit stays at 11 which fetches next 11 documents and 10 are shown as limit is set to 10.
Please check if we need to fetch one extra document for each call?

This is not regression and similar behaviour seen on 4.6.3
