Memory leak with CacheStorage/Cache/Response

When using the CacheStorage API and calling `cache.keys()` to retrieve all items stored in a cache, Safari won't free the memory of those objects.

The attached sample page opens the Cache repeatedly, and requests keys. Memory grows to several gigabytes in the span of a few seconds.
