Thanks! I'd like to verify in our build, then I'll happily merge.

I'd entertain that on the basis the changes submitted have unit tests - Is that ok?

Out of curiosity, do you have any other changes beyond the "keep existing id's" functionality?

Can you please add a test case for this?

Not maintaining this branch.

I'm going to say this use case of rendering the same heading twice isn't something I'm going to support as part of this module unless someone writes a patch.

Re-rolled for RC1.
