Description Chris Dumez 2020-02-26 15:20:27 PST 
MediaResourceLoader leaks resource responses when browsing in Safari, even though these responses are only used for testing.
AVAssetCustomURLBridgeForNSURLSession holds on to the WebCoreNSURLSession, which keeps the MediaResourceLoader alive, even if there is no media on the current page. In turn, the MediaResourceLoader always keeps in memory the last 5 HTTP responses.
