This should be changed.  If the selection doesn't touch an editing host, commands should never affect it.  Likewise, if multiple beforeInput events get fired at different editing hosts, canceling some should make the command not affect that editing host.

(I'm not prioritizing this, because it only comes up if the page has multiple editing hosts, which isn't so common.  And even then only in corner cases.)
Comment 2 Aryeh Gregor 2012-02-23 21:11:57 UTC 
After some discussion with rniwa in #whatwg: we should probably just say that if the selection is not fully contained in a single editing host, execCommand() does nothing.  Probably queryCommandEnabled() should return false in this case.  Then all this becomes simple.  I'll try doing that now, perhaps.
