WebKit's CSS3 Columns don't re-paint correctly on text-select
See the screen shot. The text selection should have wrapped all the way to the top of the second column (I started the selection in the first column and moved the mouse to the second). It seems to actually have selected all that text, just not marked the lineboxes for repaint! (Try dragging the selection to see.)

I cannot see the buggy behavior using the latest nightly Webkit. Any confirmations?
