Search Box load on the modern page takes few extra secs when the Quick launch is disabled

jcgonzalezmartin It is not quick launch presence, but quick launch after it being disabled with option in navigation settings. 

The Search box is in Top of the Quick links in the Left Corner in the new Modern Pages. 

So when the quick launch is disabled, the page should open in full view, however now it loads with some delay where we can see the search box loading and then disappearing since the quick links are disabled. 

You can see that in the below screen shot. 

Picture 1 : The loading of the search box when there is a page load. 

Picture 2 : The search box and the quick launch disappear to have full page content view. We dont need search box or the quick launch. Hence we have disabled it from the navigation settings. 

However why is this Search box Loading and consumes some extra seconds before it loads the whole page ?

While it loads, the users can hit an Esc and still click on the quick launch items or Search Box. 

This delay when hiding the quick launch with search box loading cause page load performance.
