<pre>Modern IDB: UniqueIDBDatabase's m_databaseInfo is used from multiple threads
It's meant to be assigned and used on the main thread, but in UniqueIDBDatabase::performPutOrAdd, which is a database thread method:
auto objectStoreInfo = m_databaseInfo->infoForExistingObjectStore(objectStoreIdentifier);
Yikes!
Noticed this in a random audit, don't know of any actual fallout, but it's obviously not safe.</pre>
