SVG use removed from froala editor

In my code i’d like to reuse the icons declared in the begining of the site with a code

<svg class="icon icon--96" aria-hidden="true" focusable="true"><use xlink:href="#ux"></use></svg>

The problem is that I cannot configure the editor to leave <use> tag, even tho its in the allowed attributes options.

How to overcome this limitation?

Does it still happen if the <use> tag is not empty? E.g <use>test</use>, it may be cleaning up empty tags or considers the tag invalid if used within an SVG.

I’ve added this to allow empty tags the wierd thing is on local dev it removes the use tag and on remote it leaved it.
