HTML tags on product description

Hi guys :slight_smile:

The problem: i trying to add clickable link in description for demo of my product. I use that html tag - <a href=“URL”>…</a>
Everything looks great in editor - ePad | html+css+js онлайн редактор | <!-- -->
But it doesnt work and represents as a text then i copy&paste that in product description.

Can some help my understand that i did wrong, please?

p.s. yeah im completely noob in html
