Wrong branch format shown on web page after remote upgrade

While trying to exercise bug 60695, I created a new branch in pack-0.92 format, let it get scanned, remotely upgraded it (to 2a), and only its repository format was updated on the web page. The branch format was listed as "Branch format 6", but "bzr info -v nosmart+..." correctly listed the branch format as "Branch format 7".

Steps to reproduce:
$ bzr init lp:~abentley/+junk/old-format --pack-0.92
Created a standalone branch (format: unnamed)
$ bzr checkout lp:~abentley/+junk/old-format
$ cd old-format/
$ bzr commit -m "test" --unchanged
Committing to: bzr+ssh://bazaar.launchpad.net/~abentley/%2Bjunk/old-format/
