[FIX] web: list width should not be calculated when invisible

Before this commit, the width of the headers in a list were frozen
only when the list was seen, but the calculation of the width might have
happened while it was invisible (thus giving the headers 0px).

Now, the freeze AND the calculation only occur when the list is visible
and can actually be evaluated.
