On this demo its not working:

Yeah, it seems that we parse the value but do nothing with it.  That's a layout issue, not a CSS one.

I noticed that this doesn't work.

From what I've read of the description it's supposed to not use the whitespace at the beginning and end of child elements being packed, and evenly distribute the whitespace between the child elements.

Something I could see working with navigation menus at the top of pages.

This isn't a block/inline issue.  Please don't randomly move bugs.

I wonder if the layout engine has anything for whitespace between the packed elements.

Because it has whitespace for the start and end of such elements.

When the whitespace between N objects with W whitespace leftover of some unit is something like: W/(N-1)

Yup, looks like bug 71471's patch (attachment 44288 [details] [diff] [review], landed back in 2001) added support for parsing it (by putting it in nsCSSProps::kBoxPackKTable[]), but no layout support for it.

Adding dependency on that bug.

Mass bug change to replace various 'parity' whiteboard flags with the new canonical keywords. (See bug 1443764 comment 13.)
