        <pre>Modern IDB: storage/indexeddb/cursor-continue-validity.html fails

It goes through a long series of mutations to an index while iterating the index with an index cursor.

In the good case, while on the last cursor record, it updates the object store record such that there should be an additional index record that the cursor should advance to.

In the bad case, the update happens but the index cursor doesn't realize there's a new &quot;last record&quot; and claims to be finished.</pre>
