Screen recording of bug

Steps to reproduce:
1) Open Safari Technology Preview
2) Open Settings window, Privacy pane
3) Manage Website Data...
4) Remove twitter.com cache
5) Quit Safari Technology Preview
6) Repeat steps 1 - 3

Expected results: twitter.com cache is gone

Actual results: twitter.com cache returns

See attached screen recording.

I've determined that the issue is ServiceWorkers inside the folder ~/Library/Containers/com.apple.SafariTechnologyPreview/Data/Library/WebKit/WebsiteData/Default/

If I delete the folder for origin twitter.com, then the twitter.com cache is gone. If I restore the folder, then the twitter.com cache returns.

I'm testing with Safari Technology Preview 176 (Safari 17.0, WebKit 18617.1.3.2), but the issue may have started earlier, perhaps with version 175.
