What specific section or headline is this issue about?
Events/versionchange
What information was incorrect, unhelpful, or incomplete?
onversionchange is critical and if not implemented can lead to user data corruption or loss. Running different versions in different tabs is a problem and the versionchange event solves this. Not a single thing is mentioned about this except some weak verbage of "An event fired when a database structure change was requested."
What did you expect to see?
I expect for this critical user data loss subject to be at least mentioned and even better showing some code supporting good practices for multiple tabs being open.
Do you have any supporting links, references, or citations?
Ivan V. brings focus to this critical topic Handling IndexedDB Upgrade Version Conflict
Do you have anything more you want to share?
The documentation here is pretty weak too. It just casually grazes the subject saying "was requested elsewhere (most probably in another window/tab on the same computer)" https://developer.mozilla.org/en-US/docs/Web/API/IDBDatabase/versionchange_event
