This is definitely an IDL spec bug.  Compare https://heycam.github.io/webidl/#es-overloads which checks for sequences in step 13 and dictionaries in step 14.  That is the intended behavior of this stuff, union handling is supposed to match overload resolution in terms of its behavior, and yes we purposefully added a way to distinguish dictionaries from sequences; see .https://github.com/heycam/webidl/pull/19/

I tried looking up the blame to see when the discrepancy crept in, but there are too many unrelated changes and identical-looking diffs involved to figure it out.  Anyway, we should just fix this.
