* Test addition of a new index when the existing values in the referenced
* object store have potentially unusual structured clone participants.
*
* When a new index is created, the existing object store's contents need to be
* processed to derive the index values. This is a special event because
* normally index values are extracted at add()/put() time in the content
* process using the page/worker's JS context (modulo some spec stuff). But
* the index creation operation is actually running in the parent process on the
* I/O thread for the given database. So the JS context scenario is suddenly
* a lot more complicated, and we need extra test coverage, in particular for
* unusual structured clone payloads.
*
* Relationship to other test:
* - test_create_index_with_integer_keys.js: This test is derived from that one.
