Exported deck does not contain icons file using src in styling

Shared Decks
1

I have shared this deck from ankiweb but I think it does not contain icons files in the deck.

On fresh install of AnkiDroid and importing deck does not show icon.

I have installed different version of Anki to figure out the issues, but the issues are not solved.

This is in styling of card templates Anki-xiehanzi/styling.css at main · krmanik/Anki-xiehanzi · GitHub

@font-face {
    font-family: 'Material Icons';
    font-style: normal;
    font-weight: 300;
    src: url(MaterialIcons-Regular.eot);
    /* For IE6-8 */
    src: local('Material Icons'), local('MaterialIcons-Regular'), url(_MaterialIcons-Regular.woff2) format('woff2'), url(_MaterialIcons-Regular.woff) format('woff'), url(_MaterialIcons-Regular.ttf) format('truetype');
}

The exported deck does not contain these files but it is loaded in reviewer.

I also manually pasted these files in User 2 and exported but still same issues.

_MaterialIcons-Regular.zip

Any insight will be helpful.
