Pipeline gitlab showned as “running” even though it isn't

Question

I'm using gitlab CI/CD and I have a pipeline which does the following things :

1. code verification

2. build

3. some test

4. deploy in a test environment (manual)

5. Some more tests

If we don't do the deploy, the stage 5 is useless and not "launched". (It's using the needs: ["deploy in a test environment"]). So far, so good.

The issue is: when my first three stages are complete, the pipeline is still showed as "running" even though it isn't. Here is an illustration:

I either need to manually launch the stage 4 (which would in turn launch stage 5) for it to be marked as "finished" or to manually cancel stage 5.

Please note that if I only have the 4 first stage, the pipeline will be marked as "finished" even if stage 4 was never actually launched.

So, is there a way for the pipeline to be automatically marked as "finished" at the end of stage 3 if stage 4 isn't manually launched?
