When sharing to new frontend, stop sharing with old

Cherry picked Idd465a97749328138852fee19eeba87310ccc0bc to master due to b/286408867.

Code was merged via `-s ours` and is missing even though the sha exists on the target branch. Cherry pick is required to bring in the code.

Manually remove the "Merged in" directive to allow for downstream propagation.
