Snapshot rendering of a contained Observation fails

[xlammer]

Given FSH

Profile: SomeProfile
Parent: Composition
Id: some-profile
Title: "Test profile"
* ^status = #draft
* ^publisher = "Me"
* contained ^slicing.discriminator.type = #type
* contained ^slicing.discriminator.path = "resource"
* contained ^slicing.rules = #open
* contained contains Observation 0..1
* contained[Observation] only Observation
* contained[Observation] ^short = "Observation short working"
* contained[Observation].code ^short = "Observation code short failing"

Last line fails on a HTML generation step with the following exception:
