[neverett]

Tracking issue

Re-applies the change in #4518. I opened this new PR for this change since I was unable to fast forward or rebase the branch in #4547

Why are the changes needed?

The change in #4518 was made after the monodocs branch was created, so we need to bring that change over now that the monodocs PR has been merged.
