After I write a comment and publish it, the space between paragraphs is significantly smaller than inside the WYSIWYG, as seen in the screenshot below.
To get the impression of spacing between paragraphs, I have to insert a new empy line between them. This is a bug since behaviour of identical content is inconsistent between the WYSIWYG and the saved comment.
I believe this might be related to this bug being fixed since I started seeing this problem just today.
