   - FF26- implementation does not properly convert argument to string

-- Avoided propagation of removed parts of proposals to upper stages. For example, `%TypedArray%.prototype.groupBy` was removed from the `Array` grouping proposal a long time ago. We can't completely remove this method since it's a breaking change. But this proposal has been promoted to stage 3 - so the proposal should be promoted without this method, this method should not be available in `/actual/` entries - but it should be available in early-stage entries to avoid breakage.
