The generated code has been changed in 83d207d#diff-4e672e33f445919e5aed1090a4c9babeR9

This change originates from @mprobst to support TS 2.6

If this change is required (the code looks equivalent) we should update the generation script so that it isn't overridden next time i189n data are generated.

Edit: @mprobst confirmed that the change is required. The generation script needs to be updated.
