class attribute and css binding

[Wet Feet]

What happens if I mix the HTML class attribute and also use the css binding in the same HTML element?

Would one override the other or they would merge together?

For example:

<style>
.italicized { font-style: italic; }
.bolded { font-weight: bold; }
</style>

<span class="italicized" data-bind="css: { bolded: true }">Sample Text</span>

So would the "Sample Text" end up:

1. Italicized
2. Italicized and bolded 
3. Or just bolded

you get both.
