Font formating doesnt work in the widget

Hello i really like this plugin and i wish to use it but there is problem that is stopping me. When some words of the testimonials are formatted, like for example with strong or bold html tags they show up correctly on the testimonials page, but not in the widget. Is there any way to make formatting show for the sidebar widget too ? Thank you for the answer.
