The WPT test for IDBFactory.databases() has a test for Ensure that databases() doesn't pick up changes that haven't commited.

It tests by:

• Creating a database
• Creating another database, but this time calling IDBFactory.databases() in onupgradeneeded

From my understanding, the database should exist before any attempts to upgrade the database.
Open a database connection step 6, creates a new database, and step 10.6 runs the upgrade a database

As such, the result of this

  const db1 = await createNamedDatabase(testCase, "DB1", ()=>{});
  let databases_promise1;
  const db2 = await createNamedDatabase(testCase, "DB2", async () => {
    databases_promise1 = indexedDB.databases();
    // Give databases() operation a chance to fetch all current info about
    // existing databases. This must be a sync sleep since await would trigger
    // auto commit of the upgrade transaction.
    sleep_sync(1000);
  });
  const databases_result1 = await databases_promise1;

databases_result1.length should be 2, not 1, as the test expects.

Is there something im missing here? Should maybe databases with version 0 not be counted in this?
