One of the reasons I didn't Calibre was its seeming insistence on creating its own version of my styles. Now I notice that occasionally Sigil does the same thing, most recently this:

<i class="sgc-1">

I have pondered this and come to the conclusion that Sigil has chosen to correct my instances of bolded italics. Here's the relevant style:

<style type="text/css">
i.sgc-1 {font-weight: bold}

Is there something wrong or undesirable about going <i><b>bold italics</b></i>?

Thanks!
