Thanks for this class, it's awesome.

I have a complex shortcode that is way overkill to try to display correctly in the admin. I'm using these filters https://github.com/jtsternberg/Shortcode_Button/blob/master/lib/class-shortcode-button.php#L463-L464 to just render a clean block with some text in the admin as a pseudo-placeholder, mostly so I can utilize the built-in Edit/Remove functionality.

If I had access to the original or sanitized shortcode atts, I could better customize the admin display/HTML according to a few key parameters in my shortcode.

Hope that makes sense. Thanks.
