How to include the node direction in the output of generateHtmlFromNodes?

I use $generateHtmlFromNodes to serialize the editor state to html but the output doesn't include the dir attribute. How can I add that?

Ok, I did more investigation. There is no elegant way to do this yet. Whether #1262 should be resolved or #2594 should be merged to be able to customize html serialization.
