| (pypi) Fixed the fixed-point loop that resolves self-referencing extras |
| (`pkg[extra]` entries in a package's own `Requires-Dist`). The loop compared the |
| number of extras discovered in the current round against the number known |
| before it, rather than against the size of the merged set. As a result it could |
| stop before every extra was resolved, silently dropping dependencies only |
| reachable through two or more `pkg[extra]` hops, and for the common case of a |
| package with no self-referencing extras it never converged at all, running all |
| 10000 rounds while evaluating each wheel's generated `BUILD` file |
| ([#4039](https://github.com/bazel-contrib/rules_python/pull/4039)). |
