can we add it in #3653?

I opened a separate case because it seems to me a different issue, not so urgent, and I didn't want to add complexity and delay the approval of the other PR. In fact, even with the old editor, it removes the SVGs, so it's not a bug introduced by the new editor.

@empiricompany is this still happening today?

Yes, I haven't had time to fix it yet.
At the moment I use my own extension that allows you to disable the editor for specific cms / static blocks
