Race Condition - Synchronise event: Force push on approved PR leads to merge rather than retests

[vipulgupta2048]

PR: balena-io/docs#3084

Scenario:

1. A pushed a test commit on an auto-merge PR
2. A approved the PR. PR doesn't get merged since A has committed on it.
3. B removed A's test commit and force push.
4. Instead of tests running again, a race condition happens, all conditions get met and the PR merges immediately.

Problem

My force push created a synchronized event that didn't get tested again; instead, the PR was merged.
