UI doesn't update when builds start/end/fail - require full page reload

Web UI Not Updating as Builds Finish

Every page needs a hard refresh to get latest information about builds. On a build specific page, I’ll stop getting updates at a certain point and it’ll look like the build got stuck on a step for several minutes (especially because the timers keep counting), and only on a refresh do I see it actually finished minutes ago. Same story for any of the summary pages that show multiple builds - whatever process was keeping those updated without refresh broke a few days ago.
