LPS-35931 - Comments is missing style

Hey @patrick-armitage,

I am reassigned this issue back to you since there is another issue with the comments which we need to fix.  If we edit the comment and post a reply to a user, we get the following:

I've included some source formatting to fix another alignment issue as well.
 
Please let me know if you have any questions.  Thanks!
