Ensure IndexedDB's cursor prefetch cache requests are invalidated

On success, you will see a series of "PASS" messages, followed by "TEST COMPLETE".

dbname = "prefetch-race.html"
indexedDB.deleteDatabase(dbname)
indexedDB.open(dbname)


prepareDatabase():
db = event.target.result
store = db.createObjectStore('store')
Populate with even records...


onOpenSuccess():
db = event.target.result
tx = db.transaction('store', 'readwrite')
store = tx.objectStore('store')
request = store.openCursor()


cursorSuccess():
PASS cursor.key is 0
cursor.continue()


cursorSuccess():
PASS cursor.key is 2
cursor.continue()


cursorSuccess():
PASS cursor.key is 4
cursor.continue()

That should have triggered a prefetch, injecting odd records...


cursorSuccess():
PASS cursor.key is 6
cursor.continue()


cursorSuccess():
PASS cursor.key is 7
cursor.continue()


cursorSuccess():
PASS cursor.key is 8
cursor.continue()


cursorSuccess():
PASS cursor.key is 9
cursor.continue()


cursorSuccess():
PASS continueCount is 7
PASS successfullyParsed is true

TEST COMPLETE
