SVG's Not Rendering for Image Field Type

[romanberdnikov]

I'm using the Safe SVG plugin (https://wordpress.org/plugins/safe-svg) v2.2.2 and CF v3.6. For some reason my svg files have an empty 'file_type' meta.

{
    "id": 1465,
    "thumb_url": "https://site.com/wp-content/uploads/2023/11/antihistamines.svg",
    "file_type": "",
    "file_name": "antihistamines.svg",
    "file_url": "https://site.com/wp-content/uploads/2023/11/antihistamines.svg",
    "filetype": {
        "ext": false,
        "type": false
    }
}

core/Helper/Helper.php

		if ( $attachment_metadata['file_type'] == 'image' ) {
			$attachment_metadata['thumb_url'] = $attachment_metadata['file_url'];

			if ( $type == 'id' ) {
				$attachment_metadata['thumb_url'] = wp_get_attachment_thumb_url( $id );
			}
		} else {
			$attachment_metadata['thumb_url'] = wp_mime_type_icon( $id );
		}

After a quick research, it seems like the wp_get_image_mime() function isn't reliable. It returns nothing for the SVG file (probably because of the size optimization). However, it works fine for png/jpeg: 'image/jpeg'.

And I checked '_wp_attachment_metadata' meta value, it does have a correct mime type

array(4) {
  ["width"]=>
  int(408)
  ["height"]=>
  int(456)
  ["file"]=>
  string(26) "2023/11/antihistamines.svg"
  ["sizes"]=>
  array(7) {
    ["thumbnail"]=>
    array(5) {
      ["width"]=>
      string(3) "150"
      ["height"]=>
      string(3) "150"
      ["crop"]=>
      string(1) "1"
      ["file"]=>
      string(18) "antihistamines.svg"
      ["mime-type"]=>
      string(13) "image/svg+xml"
    }
