Step 8 of can
queue a microtask to unset the active flag. It would mean:

var tx = db.transaction(…);

Promise.resolve().then(_ => {
  // transaction is now closed

…but if you want to keep the transaction open longer, that's what waitUntil
is for.

As for - this seems
fine as long as microtasks fire before step 4, which they should.
