Protractor is private and thus this test is redundant.

I see that you just added the action: merge label, but the following checks are still failing:
     status "mergeability" is failing
If you want your PR to be merged, it has to pass all the CI checks.
If you can't get the PR to a green state due to flakes or broken main, please try rebasing to main and/or restarting the CI job. If that fails and you believe that the issue is not due to your change, please contact the caretaker and ask for help.

The changes were merged into the following branches: main, 20.2.x
