Bug: approved PRs are not showing on view with "Review is Approved".

I can confirm that if I uncheck "Approved", resulting in "Review is Any", the approved PRs show. I can also confirm that if I check any of the other options (Required, Changes requested, No reviews), approved PRs don't show. The only way to see my approved PRs is to uncheck all Review options, which effectively removes the filter entirely.

在 GitHub 应用中使用“Review is Approved”筛选器重现该问题，然后跟踪 work view 的 review 筛选处理逻辑。完成的标准是：已批准的 pull request 会在选中 Approved 时出现，而其他 review 选项仍会按预期将其排除。
