ContentCssClass property is not propagated

Hi,

I want to reduce the padding of the side dialog by setting ContentCssClass, but whatever I set is not reflected in the rendered dialog. I believe it is not propagated.

Could you please check this and let me know if I am missing something? I have also tried to set and test in your online demos, but it still does not work

Fixed and will be part of our next update later Today:

I confirm it is fixed
