There was a problem hiding this comment.
Could you please add few dedicated tests? (Probably not in this test but in check-unions)

Use a join for type of a conditional expression unless the type context is a union type. A recent change (#5041) modified the type to always use a union, but this caused many problems in internal Dropbox repos that we aren't ready to fix yet.
