I just noted on the members-only list what I was able to determine from the
testcases in the source tree (like John did above). I haven't talked to
anyone involved with the current changes. While it looks like they're
following the Kyoto proposal, that proposal needs more work before I could
say whether a particular implementation conforms.

I'd really like to see a detailed description of what's currently in WebKit,
and how it's meant to work. When I tried playing around with the nightly
build to determine how multiple grids interact, it crashed.
