Suppose the following series of steps:

1. Learner open the first PR with the wrong title
2. Before the learner can fix it, the check_suite.completed event comes through (which should trigger the following step, but LL doesn't know we're there yet)
3. Learner fixes the PR title
4. LL waits for the check_suite.completed event that'll never come through.

I'm not sure the best way to handle this edge case, but it's also present in our other Actions and Apps courses.
