There is a small bug in
CMS7-9194. The whitespace between two paragraphs is only 0.3em, while looking at the changed CSS lines the intention is to change it into 1em, but due to a small mistake this is not the case.
I see in
CMS7-9194 that the following lines are added to the stylesheet:
The last line with margin-top: 0; overwrites the margin-top: 0.7em for the .cke_wysiwyg_div.cke_editable p tag. This results in .cke_wysiwyg_div.cke_editable p only having a margin-bottom: 0.3em.. The margin-top: 0.7em; for the .cke_wysiwyg_div.cke_editable p tag is always overwritten, so this cannot be correct.
The last selector should contain .cke_wysiwyg_div.cke_editable p:first-child (so with :first-child added).
