In Upgrading a database step 11 is supposed to wait for the transaction to finish.
A transaction is finished once it enters the finished state (after commit or abort)
Calling indexedDB.open("test", 1) will cause an upgrade, and then step 10.5 could change the state (via autocommit, or user action), but then we instantly set it back to inactive in step 10.6
Given the following snippet:
let db;
const open_rq = indexedDB.open(undefined, 9);
open_rq.onupgradeneeded = function (e) {
db = e.target.result;
};
open_rq.onsuccess = function (e) {
db.close();
let open_rq2 = indexedDB.open(db.name, 10);
};
Once we get to close a database connection step 3. we will be stuck in an infinite loop, because at no point has the transaction gone to the finished state. (The onupgradeneeded callback does nothing that would cause an abort or commit)
