There is an issue when using remotely linked custom fonts (TTF / OTF) to style text content in a region.
On the latest Webkit nightly the custom font text doesn't render on page load. Selecting it, where it should render, will draw it on screen.
On Chromium the behavior is spotty: the text might render on page load but it will be invisible on page refresh.

The problem is that regionOverflowRect() is used for repainting during a flow thread layout, but the flow thread's height is currently 0. Tricky.
Can probably just enforce a minimum size equal to the region content height.
Also need to disable layout state when fetching the repaint rectangle for regions, since the layout state pushed is the flow thread's and that's not going to be right.

Fixed in r97370.
There's text diff on SL: http://build.webkit.org/results/SnowLeopard%20Intel%20Release%20(Tests)/r97370%20(33870)/fast/repaint/region-painting-via-layout-pretty-diff.html
Should we just rebaseline? Or is this actual failure?
