      Multi-document transactions with read concern level local or majority perform a timestamped read at the lastApplied. Since the lastApplied is ahead of the all-committed, after the work to allow WT read at a timestamp without a snapshot, this could cause these transactions to read uncommitted storage transactions. It is essential that multi-document transactions with read concern level local read at lastApplied, so that w:1 writes are visible to these transactions. As a solution, multi-document transactions reading ahead of all-committed will not perform a timestamped read.
