Does not work for code blocks

Expected Behavior

I added a class attribute to a mermaid block

```mermaid { .ttest }

I expect the string "ttest" to be found somewhere in the exported HTML source. As like as when I add this class e.g. to a list item. This should work according to the documentation: https://plugins.javalent.com/Markdown+Attributes/Code+Blocks+and+Block+Quotes

Current behaviour

"ttest" cannot be found anywhere in the exported HTML source. Hence I deduce that on code blocks this plugin doesn't work.

Reproduction

See Expected Behavior. I export the HTML using the "Webpage HTML Export" plugin. (All other plugins are off.) In the browser in the right-click menu I choose View Page Source.
