Test that IndexedDB's cursor key/primaryKey/value properties preserve mutations.

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

PASS cursor is non-null.
PASS areArraysEqual(cursor.key, ['indexKey']) is true

Check identity:

PASS v === cursor.key is true
Check read-only:
cursor.key = null
PASS v === cursor.key is true
Check mutability:

PASS cursor.key.expando is 123

Check identity:

PASS v === cursor.primaryKey is true
Check read-only:
cursor.primaryKey = null
PASS v === cursor.primaryKey is true
Check mutability:

PASS cursor.primaryKey.expando is 123

Check identity:

PASS v === cursor.value is true
Check read-only:

PASS v === cursor.value is true
Check mutability:
