Close the Slack tab 6. Close Nightly Expected: No files? Actual: 13 files with total 3.61 MB size remain in `(profile)/storage/default/https+++app.slack.com/cache/morgue`. `cache.sqlite` only lists `https://app.slack.com/service-worker.js` which is probably acceptable, but it's 61 KB, which is way smaller than the total cache file size.
