> Have you checked how this change affects the behavior of the navigation and the index tables?

Yes. The navigation first appears in 'wide' mode for a couple of seconds. Than, on load, on a small screen, the layout is fixed. On all pages, this would be so fast, that you do not even see it. But on pages like the DS blueprints, you see it, since it still takes some times to load up. But my change avoid the layout recalculation race and boost up the page load 400% faster. I can live with that.

See all those layout and recalculation ? This is what I want to avoid.
