Thanks for the nice analysis, bnestere!
I added some comments on the PR, recommending to keep the existing behaviour and just fix the test case.

Hi Elkin, knielsen.
I've found the cause of this issue, and I'm not sure if it is a bug or intended (albeit confusing) behavior. I created PR 3468 to reproduce the failure, and track a discussion about the direction for a fix.
