Fix issue paginating executions

Editor assessment

The subject says an issue with paginating executions was fixed in the public API, which is clear about the affected surface even though the nature of the pagination fault is unstated. The fix type and public-api scope are accurate. The body is a squash list whose first bullet restates the subject and whose second, enabling all executions tests, is a concrete but orphaned fact; nothing describes what the pagination bug actually was. The Co-authored-by trailer is well formed. Style is acceptable. Clear about where, thin about what, leaving the message at mediocre teaching value rather than good.
