Accordion items’ Additional CSS class(es) not saved

Hi,

I tested your blocks on a website, and I found a bug in Accordion block.

I can add custom CSS class to the root Accordion, it works well, but If I add CSS class to an “Accordion Item” and I save the page, the class what I added to the item, not saved.

(If I close the editor, and open the page the Accordion Items’ CSS class field is empty. I checked it on the frontend too, and class isn’t found in the code.)

Greets,
Bela
