Audio atom media-id varies across page renders

[arelra]

Reported by @SHession

There seems to be an issue where the provided media ID can vary on page loads, which I suspect is the cause of the issue. As an example, on this page, I have seen several distinct values for the data-media-id on the audio element. This means we don't have a way to aggregate all the events for a single audio element because we don't have a consistent identifier.

Possible issue using elementId here which does change on every render from Frontend.

On a quick look it seems we are setting mediaId property to the elementId which is a value set by Frontend that changes on every render.
