I have a number of posts where I italicize part of the headline, usually the name of a book. In the past with version 2.*, I always used the the <i> or <em> tag. In 3.4.4, however, it ends up publishing as <i>Title</i> instead of Title.
What do I need to change to do this? I don't know if it's relevant, but I do have the Bytes for All SEO activated with "Yes" selected for "Make Post/Page Titles H1."
