Thanks for reporting this and sorry for the bug!
I think this is a duplicate of #9366 and #9345 which is fixed by #9347 which will be included in 2.1.1 which will be released sometime in the next week or two.
Please ping to have this re-opened if you can reproduce this on the v2.1.x or master branches.

Hi @tacaswell, thank you for your reply. Yes, I can confirm I can no longer reproduce this on the master branch.
