How to solve the problem with the Material+Icons font?

Question

css

I use the font ' https://fonts.googleapis.com/icon?family=Material+Icons ' for button icons. And almost always, until it loads, instead of icons, their names are tapi
* crop_free
* report
* find_in_page The

icon should take one character, and there is a whole line find_in_page
And it will hang for 10 seconds until the font is loaded

What to do?
