@marmbrus @cloud-fan Based on your comments, I did the change. Please
review the new change.
I also tried the fix after excluding the change in `attributeRewrites`. The
newly introduced test case still works fine. That means this should be the root
cause.
The fix still keeps the extra filter in `attributeRewrites`. I think it can
avoid extra compare and replacement in the subsequent transformation. Please
let me know if you want to remove the filter.
Thanks!
