Error message isn't displayed on media upload failure

[danielbachhuber]

Describe the bug

When I try to upload an image and the upload fails for some reason at the server level, the generic Error while uploading file %s to the media library. error message isn't displayed.

To Reproduce

Include this snippet locally to force upload failures:

$force_upload_failure = function( $file ) {
	$file['error'] = 'This file upload has been forced to fail.';
	return $file;
};
add_filter( 'wp_handle_sideload_prefilter', $force_upload_failure );
add_filter( 'wp_handle_upload_prefilter', $force_upload_failure );

Attempt to upload a media file and see that there isn't an error message.

#6957 is a likely candidate.

This still seems to occur when uploading files with a "Media & Text" block
