How can I force WebKit to redraw/repaint to propagate style changes?

Question

I have some trivial JavaScript to effect a style change:

sel = document.getElementById(\'my_id\');
sel.className = sel.className.replace(/item-[1-9]-selected

Since everyone seems to have their own problems and solutions, I figured I'd add something that works for me. On Android 4.1 with current Chrome, trying to drag a canvas around inside a div with overflow:hidden, I couldn't get a redraw unless I added an element to the parent div (where it wouldn't do any harm).

var parelt = document.getElementById("parentid");
var remElt = document.getElementById("removeMe");
var addElt = document.createElement("div");
addElt.innerHTML = " "; // Won't work if empty
addElt.id="removeMe";
if (remElt) {
    parelt.replaceChild(addElt, remElt);
} else {
    parelt.appendChild(addElt);
}

No screen flicker or real update, and cleaning up after myself. No global or class scoped variables, just locals. Doesn't seem to hurt anything on Mobile Safari/iPad or desktop browsers.
