            Bug ID: 233980
           Summary: A dedicated worker is not frozen even when the page is
                    in back/forward cache
           Product: WebKit
           Version: Safari 15
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit Misc.
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: hajimehoshi at gmail.com

Reproducing steps:

1. Open https://hajimehoshi.github.io/sandbox/worker/
2. See the numbers for a while
  There are two counters. The upper is counted by the main frame and the lower is counted by a dedicated worker.
3. Click 'Google.com'
4. Stay for a while (10 seconds or so)
5. Go back to the original page. The worker counter is increased for the time duration of being in google.com.
