Otherwise, children that have been transposed into a modal <dialog>'s subtree are considered inert, although they are rendered as if they are real children of the <dialog>. This is surprising to the user interacting with the dialog. I'm not sure whether ancestor/descendant should be clarified in the HTML spec or the Shadow DOM spec, and whether it should be clarified just for modal dialogs/inertness or more generally.

It's a relationship in a node tree. > > If we'd express a relationship in the composed tree, I am afraid we must say explicitly 'ancestors in the composed tree'. > > As for inertness, I've recently tried to re-define 'inertness' in the Shadow DOM spec, using the concept of the composed tree: https://dvcs.w3.org/hg/webcomponents/raw-file/tip/spec/shadow/index.html#focus-navigation > > But I am not confident about the definition of 'inertness', which is now only used in explaining 'Focus Navigation'. 94581 2 falken 2013-10-11 03:04:42 +0000 I'm not sure where the right place to spec this is. The HTML spec defines inert subtrees but there are no references to Shadow DOM in that spec. 98981 3 falken 2014-01-24 06:21:32 +0000 Since Shadow DOM hasn't changed the meaning of DOM ancestors/descendants, this bug probably won't be resolved by the Shadow DOM spec. I'll move this bug to the HTML spec. I also think there's some confusion because the HTML and Shadow DOM spec both define the term "inert". 98983 4 falken 2014-01-24 06:26:40 +0000 Moved to https://www.w3.org/Bugs/Public/show_bug.cgi?id=24379
