QWebElement::geometry() may return an unexpected value if there is a re-layout pending

If style or content changes have recently been made to the HTML element represented by a QWebElement or its children then WebKit may have scheduled an asynchronous layout which has not happened yet, so the geometry returned by QWebElement::geometry() may not match what the developer is expecting.

The problem can be worked around by fetching a CSS style property which depends on the element's size before calling geometry():

// fetch a CSS property which depends on the size of the elemement
// to force WebKit to process any scheduled re-layout events for this element
QString widthProperty = element.styleProperty("width",QWebElement::ComputedStyle);

A solution would be for QWebElement::geometry() to force a layout before returning a result, but that may not always be desirable given the performance impact. An alternative would be to simply document this gotcha.
