using imageToDeploy with a latest tag does not update revision

I want to use this action to deploy "an already pushed application image".

In the CI/CD pipeline I create and push the image to the repository with the `latest` tag. However, when I specify the imageToDeploy parameter as: registry/image:latest everything works fine, however it will not create a new revision. The old revision stays online, until a new container is spinned up by a ACA scaling rule.

Is this a design choice? For now I am using specific version numbers as tags, which works. But I would like to be able to use a `latest` tag, which represents the currently running version.
