Article comment area is not good

many people write article for this web site and at the end of the article there is commnet section where pople write comment for the article. i have seen when i try to post bit more text in comment area with few sentence with new line and indentation then i saw when we post then text becomes very clutter and no new line or indentation is maintain.

 

so please guys fix this problem. if we post few sentence with new line and indentation then it should not be lost after posting the text. looking for fixing it. thanks
