#15006 caused https://github.com/microsoft/TypeScript-DOM-lib-generator/pull/1284/files#r825015464, where IDBDatabase.onabort support is now unable to be inferred from BCD.

Basically BCD is removing all data for bubbling events, and there's no machine-readable data about which events bubbles to which interfaces, AFAICT.

(And this is again a logical breaking change: #12250)
