Why is a font being downloaded many times from fonts.googleapis.com?

Question

Google Fonts

Good afternoon!
I included the font from google fonts in the less file:

@import url('https://fonts.googleapis.com/css?family=Open+Sans:400,600,700,400italic&subset=latin,cyrillic');

As a result, I see:

But the main problem is that after the next loading of fonts, the text blinks, and the problem manifests itself in Chrome and does not appear in Firefox.
All requests are made to an address like https://fonts.gstatic.com/s/opensans/v13/{different hash here}.woff2 Can
you please tell me how to remove this multiple loading and/or blinking of the text?
