Adding an additional field to WIQL removes resulting columns

Execute this query in Wiql Playground

SELECT
[System.Id],
[System.WorkItemType],
[System.Title],
[System.State],
[System.AreaPath],
[System.AreaLevel1],
[System.AreaLevel2],
[System.RelatedLinkCount],
[System.IterationPath]
FROM workitems
WHERE
[System.TeamProject] = @project
AND [System.WorkItemType] = 'Epic'
AND [System.RelatedLinkCount] > 1
ORDER BY [System.ChangedDate] DESC

And you get all the columns. Add [System.History] to the projection and the ID, AreaLevel1, AreaLevel2, and RelatedLinkCount fields magically disappear!
