Update the html lang attribute #967
Description
Hi,
In an application, I have the lang attribute set on the <html> tag.
When the user switches the locale, the body is changed with Turbo.
However, the lang attribute is not updated by Turbo, and some of my JavaScript relies on this attribute to use the correct locale.
I know that I could either add an event listener listening to a Turbo event to update the attribute, or trigger a full page refresh instead.
Would it make sense for Turbo to also update the lang attribute by default instead of adding custom logic?
