Push moving whole page instead of page-wrap content area for mobile

[bustarice]

So while using push on desktop view, it pushes my content div fine and my navbar on top stays put.

However when I open mobile view the whole page pushes right including the navbar.

I temporarily changed the navbar to position: absolute just to see what will happen and it then pushed only the content of page-wrap. This is not a solution obviously because the navbar needs to be fixed and sticky in my use-case. This is probably un-related but did it just to see.

So I'm not sure why in desktop works fine but mobile the whole page pushes instead.
