Implicit receiver type inside expect class is inconsistent with the
type resolved from an explicit reference inside that class. The former
one is a default class type, i.e. expect; the latter one resolves to
an actual type when either expect and actual are in the same module, or
when the sources are compiled for a particular platform.
The workaround is to manually actualize implicit receiver type for one
particular check affected by the broken subtyping.
