[webkit-dev] AbsoluteClippedOverflowRect return empty IntRect

[tonikitoo (Antonio Gomes)]

Hey all.

I am facing a strange issue while trying to the get repaintable rect
of a given Node* object. In my code I am doing something like:

(...)
ASSERT(node);
node->renderer()->absoluteClippedOverflowRect();
(...)

, where "node" is a valid reference to an <a> in the following simple
html sample in http://pastebin.ca/1850582 (see id="it").

In the sample, "node" is an offscreen anchor in a scrollable <div>,
and calling absoluteClippedOverflowRect returns an empty IntRect to
me. If I scroll until it (the node whose id is "it") gets visible, and
then trigger my snippet code above it returns a valid value. Also, by
doing static_cast<Element*>(node)->getRect() I get the same valid rect
returned.

I am wondering if it is an expected behavior or a bug?

Regards
