I agree that zoom should work as you describe, but it won’t work that way if the browser is sending the wrong message regarding the viewport. The viewport should not change when the page is zoomed in on. I think that most users would expect that zooming would enlarge a protion of the viewport, and that is what it should do.

Otherwise breaking this zoom would make the content less accessible, but perhaps a workaround would be to add a font size toggle in the header of the website where users can increase or decrease just the font size. Since I read you were using jQuery, check out this code that does what I described really neatly: http://codepen.io/ianfarb/pen/sxbvk .
