Langage list mispositionned (mis-anchored)
Issue
In #about, the langage selector is fixed to the top of the page and doesn't take into account the user having scrolled down.
Steps for reproducing the issue
- Select "about"
- Scroll down
- Click to change langage Screen gets dimmed but options are at the top of the page and thus not visible.
