Comment:

 I did some testing on this today. Here's what I found.

 In the Classic Editor, the behavior is as follows:
 - Clicking "Add Media" and selecting "Insert from URL" leads to the file
 being embedded as an HTML link.
 - Inserting a `[audio fileurl="urlthatisaredirect"]` leads to a shortcode
 preview that just hangs in the loading state.

 In the block editor, the behavior is as follows:
 - Inserting an audio block and clicking "Insert from URL" successfully
 loads the audio player with the correct track length displayed in the
 player. However, the audio cannot be previewed as none of the controls
 work. This seems to happen regardless of whether the audio block is added
 using a URL or by selecting an audio file in the media library. Even after
 the page is reloaded, I still cannot preview an audio block. Viewing the
 page on the front-end, the players are all usable and correctly process
 the 302 link.

 I'm wondering if this has to do with the function calling
 `wp_check_filetype()`, which attempts to match a file type from a file
 name. Because the URL does not include an extension, the function is
 unable to accomplish that and `wp_audio_shortcode()` is returning without
 any generated HTML to display an embed.

 I have not had a chance to look into how the block editor implementation
 is different, but the code responsible for generating the audio block
 preview is doing something different. I'm going to move this back to the
 Media component as it seems something is going on with the shortcode or
 media related code and not the MediaElement.js code.
