Review Comment:
I don't think this is the only place that needs to be fixed. I did a quick
check and I think there are a few other places that also need to be fixed. We
should also add some additional tests for the other places that fail without
the fix and pass with it.

It's possible that there are a few more places in Spark as I haven't done a
thorough analysis, so it would be good to fix those places as well
