Load language icons earlier [#2833560]

Hello,

I am using Language Switcher Dropdown and Language Icons modules.

When my page is loaded on the smartphone the Language Icons are loaded at the end of page loading: All elements (logo, mobile menu, header image, content, text, footer) are loaded earlier. The Language Icons are loaded at the end and this looks not nice.

During loading the site (I already can see the logo, the mobile menu, the header image, the text ...) the language icons are not here!
After the whole site is loaded in the browser the language icons appear.

This is not fine, the language switcher icons should be loaded as fast as all the other elements.
