I guess that the problem is that positioned items support hasn't been ported yet to WebKit.
We've an almost finished implementation on Blink, but we're waiting for CSS WG to be sure it's 100% fine, and then we'll port it to WebKit.
The problem is that we're not skipping the positioned items during grid layout and probably those ASSERTs come from the patch in Blink.
We might remove the ASSERTs or start doing the basic stuff for positioned items, like skipping them as they don't affect the layout of the grid. And in the future we could make them work properly according to the spec.</pre>
