E.g. see https://bugs.webkit.org/show_bug.cgi?id=262359#c2 where EWS landed this commit: Committed 266719.77@bugfix/NetworkProcessConnection-2.42 (e92f5f33fd26): <https://commits.webkit.org/266719.77@bugfix/NetworkProcessConnection-2.42> The pull request was from source branch bugfix/NetworkProcessConnection-2.42 into target branch webkitglib/2.42. The canonical identifier of the commit should always match the target branch; i.e. it should end in @webkitglib/2.42, not @bugfix/NetworkProcessConnection-2.42.
