Description Anne 2015-02-10 15:35:35 UTC 
"If any condition which affects the distribution result changes, the distribution result must be updated before any use of the distribution result."

It seems both layout and events make use of the distribution result. That would be worth mentioning I think to make it clear what the observable bits are.

However, if events make use of them, wouldn't we be able to work out when distribution happens by firing synthetic events?

And how does this work for ranges that can reach into the shadow DOM? Wouldn't we get problems there too with how deterministic things are?

See also bug 28443 which discusses this very same issue.

This might be moot if we get an API.
