@sahil143 verified locally works as expected, however currently with just this changes if the revision is not in traffic block it'll appear outside service box. IMO this should be handled as part of #3288

@serenamarie125 FYI, service block will be empty as in the description till revisions are ready and receive traffic

@invincibleJai I rebased with you PR locally and this is fixed in your PR #3288. I can no longer see revision outside the service box if they do not have traffic
