Is there a way to force it so the popup stay

If you enable panels at "chrome://flags/#enable-panels" you can use something like:

chrome.windows.create({
    url:"popup.html",
    type:"panel",
    width:300,
    height:200
});

to open a panel window instead which will stay on top all the time as long as you don't move it from the bottom of the screen.
