Why is this only failing on Windows; shouldn't Linux fail in the same way?
Does this indicate that there is a backwards compatibility issue with XAR file import?

Yes, it should, but there was a problem related to / vs \ so we skipped an intended check on non-Windows. Fixed in the related platform PR.

As for backwards compatibility, yes, there's a potential concern, but hopefully not in the real world. The test was setting pipeline root in a place that didn't cover the whole tree of imported files, which shouldn't be common.
