        <pre>Modern IDB: storage/indexeddb/transaction-scope-sequencing.html fails

The test is sound, and Modern IDB's transaction scheduler is non-complaint.

tx1 blocks tx2, and tx2 blocks tx3.

Our scheduler starts tx1, then sees that tx2 is blocked so it passes over it. It then sees that tx3 is *not* blocked by in-progress tx1, so it starts tx3.

But the spec actually says any previous transaction that overlaps with your scope must run to completion before you get to run.

So because tx3 is blocked by tx2, it can't run until tx2 finishes. Which means tx3 is implicitly blocked by tx1.

The fix will be easy.</pre>
