When adding a custom CSS class to the cancel button on a form (mainly used to style and theme based on the branding of my company) it gathers the custom class say, "cancelBtn" and also the other classes, but doesn't have the space between the custom and the form added classes.
So the button now looks like (with custom class)
<input type="submit" XXXXXXX class="cancelBtnfn-cancel-button nf-disableonsubmit" XXXXXX>
Anyone else see this as well? Possible bug?
