For Bugs and Features; did you add new tests?

No, but the bug is in a test.

Motivation / Use-Case

Solves this issue: #1734.

I ran into this issue while creating a fix for this: #1703. The fix I made for that problem extends the initial compilation time and makes the Routes test fail, so I thought it would be good to solve this before going further.

Breaking Changes
