We initially added this in D203062, but remove it in D212064. The reason of removing it is because not setting up the status for a newly created MDSM causes Netflix's problem. However, the situation of reinforming metadata load still exists, eg. switching from the media engine playback to the normal playback, which could be seen in the clearlead situation. That seems a possible case to hit the assertion [1]. Therefore, we should add back the mechanism of not informing the metadata load again, but also keep the status being set properly. In addition, we will handle the process of dispatching `loadedmetadata` properly in bug 1906206.
