Oh, no... I just find there's already an opening PR #193 which tried to address the same issue. 😭😭😭

Gently ping @tanmaykm . Could you help to review both PR?

The solution in #193 is to update attrib.ptyp directly and mine here is just a workaround (but should be much easier to review and merge 😆 ).

(Also cc @neveritt)

Thanks @findmyway !
I just merged #193. Hope that works for you too. Shall tag a new release in a bit.
Sorry for the delay.
