Due to the many merge conflicts created from #47106 against the 2017.7 branch
and #46002 against the 2018.3 branch, the changes from #47106 have been largely
removed from this merge forward and the HEAD of 2018.3 was taken.
A separate fix for Tornado 5.0 support will need to be made directly against the
2018.3 branch.
