Hyperlink HTML markup not working

Hi there.

I lover your plugin but I am having problems hyperlinking in HTML markup in Page builder (Beaver) module editing screens, eg: https://drive.google.com/file/d/15Z6RoTD_oEMEtTgi4u_2KCXU-dESMKs4/view?usp=sharing

Eg This code (In Text mode):

<div class=”player-link”>
<i class=”fas fa-headphones fa-2x”></i>
</div>

Some of the HTML markup disapperas and changed to this (when I return to edit it):

<div class=”player-link”></div>

Note, this is the CSS:

/* player icon links */
a.player-link {
color: #ffffff;
}
a.player-link:hover {
color: #cccccc;
}

The page I need help with: [log in to see the link]
