How to separate approvals of multiple jobs

Question

I have a release pipeline that consists of two jobs, for QA and Production. Each job has a corresponding environment:

jobs:
- deployment: QA
  displayName: QA Deployment
  environment: QA
...
- deployment: Production
  dependsOn: QA
  displayName: Production Deployment
  environment: Production
...

And each environment is set to request an approval:

I expected to have a separate approval for each job, i.e. to be able to approve the QA job and run it, and not to have to approve the Production job. But for some reason, I am not able to run the QA job without approving both QA and Production. So I can run either both jobs or none. What am I doing wrong, and how can I fix this?
