versionchange is super important and hardly is given any attention

### MDN URL

https://developer.mozilla.org/en-US/docs/Web/API/IDBDatabase

### 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](https://dev.to/ivandotv/handling-indexeddb-upgrade-version-conflict-368a)

### 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)"
