 If the current user database has a higher version than in the `open` call, e.g. the existing DB version is `3`, and we try to `open(...2)`, then that's an error, `openRequest.onerror` triggers.
 
 That's rare, but such a thing may happen when a visitor loads outdated JavaScript code, e.g. from a proxy cache. So the code is old, but his database is new.
