agl has just closed agl's pull request 2123 for https://github.com/w3c/webauthn:

== Add the `topOrigin` field to the limited clientData verification algorithm ==
I was asked to to the PR for this issue, without looking at the submitted PR, in order to avoid IPR issues that would arise from a change by a non-member.

Fixes #2102

Implementation commitment:

(Omitting due to minor nature of the change.)
