Comment (by adamgundry):

 I've taken an initial look at this. FWIW it seems I need `:browse!` to
 observe the difference.

 The problem is that `browseModule` uses `modInfoExports` or
 `modInfoTopLevelScope`, both of which omit record fields defined with
 `DuplicateRecordFields`. To change this `browseModule` needs to be
 modified to work with a mixture of `Name`s and `FieldLabel`s, which is a
 bit of pain. I'm thinking about how to redesign things to make this
 easier...
