Prevent invalid empty id attributes. #4090

Closed digitaldonkey closed 3 years ago

Setting id Attribute for cloned slides empty results in invalid HTML as the id attribute must not be empty and multiple empty id attributes result in a "duplicated id" validation error.

I know that is pretty cosmetic, but required in my ARIA review.
