## Context
In CI, we are still retrying feature specs when they fail (we want to stop doing this with https://gitlab.com/gitlab-org/gitlab/-/issues/449030+).
## The problem
The `ee/spec/features/projects/settings/ee/protected_branches_spec.rb` spec (and its FOSS counterpart, `spec/features/projects/settings/ee/protected_branches_spec.rb`) are being retried a lot, and **they are causing CI/CD job timeouts**:
1. https://gitlab.com/gitlab-org/gitlab/-/jobs/8936448614#L1579
2. https://gitlab.com/gitlab-org/gitlab/-/jobs/8937668233#L900
3. https://gitlab.com/gitlab-org/gitlab/-/jobs/8915646421#L1933
## Goal
Make those feature specs **more stable**, so that we can eventually stop retrying them for them to pass.
