IDB freezes on extension updates

[twschiller]

Context

• https://pixiebrix.slack.com/archives/C0436P48QHY/p1709742510204439
• Symptom is the the Extension Console does load, mods don't run, etc.

Discussion

• In the past we've had problems where we weren't correctly closing IDB connections
• We have an IDBErrorDisplay for use with ErrorBoundary. However, what's happening is the request just hangs, it doesn't error

Workaround

• Workaround is to close/reopen Chrome. NOTE: reloading only the extension does not resolve the problem

Potentially Related Issues

• IDB might be related to crashes like this: AA notifications mod crashing browser on activation/after use #7753

Known IDB Issues

• Internal error opening backing store for indexedDB.open #6655

One idea we could implement is a hook/component that tries to perform a pageRegistry:count() call on IDB, and sets a flag to true if it doesn't get a response in a few seconds (and can clear the flag once it gets a response, or the call errors)

The UI can then show a modal or banner saying: "We're having trouble connecting your browser's local database, please close and reopen your browser.". It could also include a link to our troubleshooting docs: https://docs.pixiebrix.com/how-to/troubleshooting
