HTML lang attribute does not change

[doudbanks]

Current behavior

When changing the language through setDefaultLang(param);, the lang attribute of the html root ellement in the dom does not change, it's a major issue for screen readers ...

Expected behavior

HTML lang attribute changes.

How do you think that we should fix this?

Select the attribute and change his value when the language is changed.

Minimal reproduction of the problem with instructions

Just change the language using setDefaultLang() and check the html root element via the chrome inspector.
