I have been able to make reusable paragraph blocks without too much of a learning curve to deal with, but I'm flat out hitting the wall trying to take a Gutenberg blockquote block and changing the class name so that I can differentiate it from the standard Gutenberg blockquote block. No matter what I try to change it to, it wants to try to revert back to wp-block-quote.
I binged (B)ing (I)s (N)ot (G)oogle around for an answer, but nothing that I could make use of came up. I cannot understand why a paragraph tag will allow me to assign class names for reusable blocks, but the blockquote tag is being a problem.
I'd appreciate some help on this if anyone cares to lend me a hand. Thank you.
