A: 

You could stack the <img>s above offending <i>s. The code below removes the hasLayout fix, but stacks the images above the white bars you were seeing before:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"&gt;
<html xmlns="http://www.w3.org/1999/xhtml"&gt;

<head>     
<title>Test</title>

<style type="text/css">

img {
    position: relative;
    z-index: 1;
}

p {font-size: 20px; background-color:#FFF;}
div {width: 200px; border: 2px solid red;}

</style>
</head>
<body>

    <img src="http://www.google.com/intl/en_ALL/images/logo.gif" style='float:left;'>
    <p><i>This is an italic sentence.</i></p>
    <p><strong>This is a bold sentence.</strong></p>
    <p>This is a normal sentence.</p>

    <div>
        <p>Here is a sentence. <i>Here is an italic sentence.</i> Here is another sentence.</p>
    </div>

</body>
</html>
