UpdateRevision with SaveChangesAsync generates a ConcurrencyException

[ivanoterrivel2]

I want to use SaveChangesAsync after calling the UpdateRevision method.

On Marten solution, in numeric_revisioning.cs test files, for the public async Task optimistic_concurrency_failure_with_update_revision()
If I change the SaveChanges() to use SaveChangesAsync() it throws a Marten.Exceptions.ConcurrencyException.
The tests with UpdateRevision seem to fail when used with SaveChangesAsync();

[Fact]
public async Task optimistic_concurrency_failure_with_update_revision()
{
    var doc1 = new RevisionedDoc { Name = "Tim" };
    theSession.Store(doc1);
    theSession.SaveChanges();

    doc1.Name = "Bill";
    theSession.Store(doc1);
    theSession.SaveChanges();

    doc1.Name = "Dru";
    theSession.Store(doc1);
    theSession.SaveChanges();

    var doc2 = new RevisionedDoc { Id = doc1.Id, Name = "Wrong" };
    theSession.UpdateRevision(doc2, doc1.Version + 1);
    await theSession.SaveChangesAsync();

    theSession.Logger = new TestOutputMartenLogger(_output);

    await Should.ThrowAsync<ConcurrencyException>(async () =>
    {
        theSession.UpdateRevision(doc2, 2);
        theSession.SaveChanges();
    });
}
