| This test is checking that AudioContext is deleting after navigation. |
| It is not possible to count AudioContext objects directly. |
| But we could use Native Memory Snapshot which has information about Page.Audio.SharedData. |
| All the shared data are retained by HRTFDatabaseLoader refcounted singleton |
| and Native Memory Instrumentation is visiting it via public getter. |
