When using a Text Section, text will wrap on Internet Explorer 8 but not on Firefox 8.
Text is truncated in "Text Section" (Firefox 8.0)
I'm not very familiar with CSS but I noticed that if I set the style of the <div class="sectioned-view-info"> element to "white-space:normal; word-wrap: break-word;" this resolved the problem.
