Issue with Rich Text Editor Source Code

Having an issue where I had a span tag inside an anchor for Font Awesome. Something like this:

<a href="location.com">Link Text <span class="fas fa-chevron"><span></a>

But it doesn’t save the span. I have instance of this working across my site, but if I make edits they go away and that span isn’t showing up in any of the other rich text editor modules.

Any suggestions?

<a href="location.com">Link Text <span class="fas fa-chevron"> <span></a>

Hello mate,
You can use like this. its working fine.
Thanks
