Placing styles in paragraphs causes line breaks to be lost (compacting paragrphs)

Create a wiki asset block that contains four paragraphs. (Or just look edit this asset: http://dev.curriki.org/xwiki/bin/view/Coll_jmarks/StylesinParagrphstestunderscoreintitleoo )

In Paragraph one select just normal text

In Paragraph two, select two works and change the fonts and or color of each

In paragraph 3, select three words in the middle and change font, then select the one work in the middle of those can change its color

in paragraph 4, select three forks and change font and or style, and then select the last word of that and then select two more words afterword and select a text style for those (Overlap styles)

Now save and edit again OR switch to pure Wiki mode and back. In both cases the paragraphs are concatenated/compacted (the breaks removed between the paragraphs.)
