This issue arises from #417. See that PR for more context.
@jacadzaca mentioned at #374 wired test cases. Those where refactored in #417 but the quirk remained in place. At this place and maybe at other locations, there are custom components without the "X-" prefix, so they should be IANA registered names. Since this is not the case, I suggest changing them to x-names since then the test case parses valid ics.
[ ] Update test cases touched in #417.
[ ] Search for other tests with custom components that may do the same thing.
