While working in the current state of the website configuration, the
overlay computation was not working anymore in case the scrollbar is
moved out of the wrapwrap. Indeed, in that case, the position was wrong
by the amount of the page scrolling.
While we could include that scrolling value in the equation, this commit
chooses to restore the way it worked before the "website-in-backend"
merge at [1]: making the overlay be naturally positioned according to
the page scrolling wherever the scrollbar is. To do that, the overlay
had to be moved inside the content (the website iframe) which has the
disadvantage of risking the overlay design being broken by a theme. This
solution was chosen as it simplifies the code, and potentially allows
for performance improvements in the future: not forcing a position
recompute after each scroll (the animation should already be smoother /
more performant this way). This will actually be needed for another fix
/ improvement: the background image overlay has to be in the iframe too.
Note: a further commit will move back the scrollbar behavior out of the
`#wrapwrap`, this is thus especially needed.
