+    // initialization is not always honored by the underlying player — the UI state
+    // reflects the desired track (selectedAudioTrackId in core) but the actual
+    // playback uses the player's default track (the first / index 0). This is
+    // observable on LG webOS Smart TV (see issue #2564). Symptom: user re-selects
+    // the already-highlighted option and only then does the audio actually switch.
+    //
+    // Fix: don't mark the selection as "done" until the player's
+    // selectedAudioTrackId actually matches the desired id. Until they match,
+    // keep retrying on each render of audioTracks / selectedAudioTrackId / streamState.
