--- Comment #2 from Gregg Tavares <gman at chromium.org> ---
Also note, setting the containers CSS dimensions fixes the issue although it appears compositing has to happen at least once. In other words

    container.style.width = "401px"; container.style.width = "400px";

doesn't work but

    container.style.width = "401px";  // change container size temporarily
    setTimeout(function() {
      container.style.width = "400px":  // change it back
    }, 200);

Sounds like some internal flag just needs to be set to fix this
