Gutenberrg Editor – Drop Cap Size??

Yes, I finally heard the news. Gutenberg is coming my way. Like it, or not. So, I decided to jump in. It does seem okay and it will take some getting used to.

Here is my question. I notice that I can add “Drop caps” for the initial letter in a paragraph. This is a very nice idea; except for one thing. The letter is way too big for my taste. How do I change the size of the drop cap size to be 18 and normal text at 12. The numbers are font sizes. I tried to create a class called “has-drop-cap” and set the size to MEDIUM; not large.
