It did not when I merged the mm-hotfixes branch, but then I refetched
your trees during the day and so that patch appeared when I merged the
mm tree (which is now based on a later version of the mm-hotfixes
branch). So next-20221125 as a whole will not have the build failure.

After I merge all the "fixes" branches, I upload a "pending-updates"
branch that feeds into the various bots independently of the full next
tree.
