Default language cached in sessionStorage from HTML can have messed up line breaks

Trying to debug this myself, found the problem in the innerText specs, quoting:

If the element itself is not being rendered (for example, is detached from the document or is hidden from view), the returned value is the same as the Node.textContent property.

I can't think of a workaround for this without making assumptions about the text content itself (for example, only preserving newlines after a period).

• Is storing the default language in the html itself a good idea?
  Motivation was/is some basic SEO without needing SSR, otherwise the default content will need to be retrieved from a json and added to the HTML in runtime.

I think making sure served HTML default translatable content respects desired visual line breaks is the easiest workaround for now.
Will add a note in README for now.

What about using innerHTML instead of innerText?
This way we could get closer to React's <Trans></Trans> component functionality, that is, respect markup inside translations.

Downside is the danger of inserting HTML from json files...

Will reopen to try this out, or give more thoughts to it.
