Testimonials in the Safari browser

Hello!
My problem is how the testimonials look in the Safari browser. But in the Chrome browser it looks normal. I mean, the text in testimonials is partially displayed and not all letters are displayed. I think it can be problem with Russian language, because when I write this text in English, then testimonials start to work correct.
What can I do to fix this?

It’s displaying fine to me as seen in the below screenshot. Are you running the latest version of Safari?
