Original Description
sorth.js makes some sorted queries on an index and expects the documents to come in a certain order. It's not clear that the order of documents is guaranteed in some cases. On WiredTiger, the test can fail because a different document is returned first from the index.
In the following case, we did a query on a descending index with a descending sort. We expected to get { a:1, b:3 }, but instead we get { a:2, b:3 }. The index keys for the index used for the query do not include "a".
