    Not only secrets, but anything, if masked, cannot be referenced into another job:

e.g. when I use amazon-ecr-login get a registry in outputs,
https://github.com/marketplace/actions/amazon-ecr-login-action-for-github-actions

      REGISTRY: ${{ steps.login-ecr.outputs.registry }}
outputs:
    registry: ${{ steps.login-ecr.outputs.registry }}

but if I define the registry into output for another job to use, the full registry string is masked like this:

Logging into registry ***.dkr.ecr.ap-southeast-1.amazonaws.com

in another job, use it with jobs.job_id.outputs.registry it got empty

this is a BUG, not only enhancement request in community/community#13082

Start by reproducing the amazon-ecr-login workflow described in this issue, focusing on the step output, the job output, and the later jobs.job_id.outputs.registry reference. Trace how the runner masks values and transfers outputs between jobs. Done means a masked registry value is not lost when exposed as a job output, with masking behavior still intact.
