Why is the font broken in Safari?

Question

css

On the site in the forms of the client (Mac, Safari) the font breaks.

Open Sans font. I connect via Google Fonts:

<link href="https://fonts.googleapis.com/css?family=Open+Sans:300,400,800&amp;subset=cyrillic,cyrillic-ext" rel="stylesheet">

Moreover, OpenSans is on the entire site, but it breaks only in forms.
