### Summary
MR Approval Policy for Newly Dismissed Vulnerability Only takes affect After Rerunning the Pipeline
### Steps to reproduce
1. Create a policy as follows
```yaml
approval_policy:
- name: newly_dismissed_vul
description: ''
enabled: true
rules:
- type: scan_finding
scanners: []
vulnerabilities_allowed: 0
severity_levels:
- critical
- high
vulnerability_states:
- new_dismissed
branch_type: protected
actions:
- type: require_approval
approvals_required: 1
role_approvers:
- developer
- type: send_bot_message
enabled: true
approval_settings:
block_branch_modification: true
prevent_pushing_and_force_pushing: true
prevent_approval_by_author: true
prevent_approval_by_commit_author: true
remove_approvals_with_new_commit: true
require_password_to_approve: false
fallback_behavior:
fail: closed
```
2. Introduce New vulnerabilites via an MR
3. Dismiss the Vulnerability
4. MR status does not change and still can be merged
5. Re-Run the MR pipeline, the policy gets evaluated and MR status changes to approval needed.
### Example Project
<!--If possible, please create an example project here on GitLab.com that exhibits the problematic
behavior, and link to it here in the bug report. If you are using an older version of GitLab, this
will also determine whether the bug is fixed in a more recent version.-->
### What is the current *bug* behavior?
Policy Only gets evaluated after Re-Running the pipeline
### What is the expected *correct* behavior?
After a vulnerability dismissal, the MR approval policy should also gets evaluated and blocks the MR.
### Relevant logs and/or screenshots
1. New Vulnerabilities introduced
{width=970 height=681}
2. Dismiss the Vulnerability
{width=949 height=671}
3. MR can still be merged (should require an approval since vulnerability is dismissed)
4. Re-Run the same pipeline manually
5. Status changes to Requires Approval.

### Possible fixes
<!--If you can, link to the line of code that might be responsible for the problem.-->
### Patch release information for backports
If the bug fix needs to be backported in a [patch release](https://handbook.gitlab.com/handbook/engineering/releases/patch-releases) to a version
under [the maintenance policy](https://docs.gitlab.com/policy/maintenance/), please follow the steps on the
[patch release runbook for GitLab engineers](https://gitlab.com/gitlab-org/release/docs/-/blob/master/general/patch/engineers.md).
Refer to the [internal "Release Information" dashboard](https://dashboards.gitlab.net/d/delivery-release_info/delivery3a-release-information?orgId=1)
for information about the next patch release, including the targeted versions, expected release date, and current status.
#### High-severity bug remediation
To remediate high-severity issues requiring an [internal release](https://handbook.gitlab.com/handbook/engineering/releases/internal-releases/) for single-tenant SaaS instances,
refer to the [internal release process for engineers](https://gitlab.com/gitlab-org/release/docs/-/blob/master/general/internal-releases/engineers.md?ref_type=heads).
