Review Comment:
Made the change in 1629228. That alone fixes my problem because
`UnresolvedAttribute(Seq(s))` doesn't go through `parseMultipartIdentifier`
which drops the backticks.
I kept the `override val` as it seems unnecessary to create a new
`UnresolvedAttribute` if `DslAttr` already wraps one. But happy to revert and
just go with the change you proposed.
