thanks question.

you transactioninactiveerror because delete operation want preform happens in callback of ajax call.

the indexeddb autocommitting, meaning once actions on transaction done, transaction commits. meaning in case, once results in cursor iterated, transaction commited. transaction doesn't wait on possible calls can made due async callback.

so should delete item or open new transaction every delete.
