LPS-42251 - Size 72 title is cut off in Web Content in preview

Hi Jon,

Attached is an update for https://issues.liferay.com/browse/LPS-42251.

The fix should now extend to the preview as well.  I squashed my changes into the same commit as before.  I had to wrap the preview in a div with a new class in order to target it.

Please let me know if there are any issues.

Thanks!
