[BUG] workflow filter "is:complete" fails to show events after 3 Aug

Hi. When I filter GitHub workflow runs using is:complete, I only see events up to 3 August. Since then events are being generated, and they’re completing, but they’re not appearing in this filter.

I checked three of our private repositories, all are affected.

It can be seen on GitHub’s own public repos here:
Actions · github/codeql-action · GitHub

(note that the skipped run does appear)

Here’s the list without the filter, showing more recent completed runs:
Actions · github/codeql-action · GitHub
(sorry forum blocks attaching another image)

This affects the API as well:

~ curl -sS 'https://api.github.com/repos/github/codeql-action/actions/runs?status=completed' | grep created_at | head -5
      "created_at": "2021-08-05T23:55:38Z",
      "created_at": "2021-08-03T11:02:22Z",
      "created_at": "2021-08-03T11:02:22Z",
      "created_at": "2021-08-03T10:50:48Z",
      "created_at": "2021-08-03T10:50:48Z",
~ curl -sS 'https://api.github.com/repos/github/codeql-action/actions/runs' | grep created_at | head -5 
      "created_at": "2021-08-09T09:01:40Z",
      "created_at": "2021-08-09T00:05:17Z",
      "created_at": "2021-08-08T00:05:08Z",
      "created_at": "2021-08-07T00:04:32Z",
      "created_at": "2021-08-06T00:04:54Z",
