Bug 80900 – (register|unregister)DynamicSubtreeNodeList should be called only for labels and regions node lists

• Component: DOM
• Status: RESOLVED FIXED

[Ryosuke Niwa]

I don't think we need registerDynamicSubtreeNodeList and unregisterDynamicSubtreeNodeList.

In particular, the following comment seems no longer valid because TreeScopeAdopter::moveTreeToNewScope clears node list caches whenever nodes are adopted into a new tree scope.
    // We haven't been receiving notifications while there were no registered lists, so the cache is invalid now.
    if (data->nodeLists() && (!treeScope() || !treeScope()->hasNodeListCaches()))
        data->nodeLists()->invalidateCaches();

Ugh... this isn't quite right because of LabelsNodeList and RegionNodeList. They need to be notified of changes at the document level instead of at the node it belongs :(

[Ryosuke Niwa]

Changing the scope of the bug a little bit.

ugh.... regions node lists were passing tests due to "redundant" cache invalidation magically updating otherwise stale node lists :-(

Apparently I mangled patches together when I was landing a patch for https://bugs.webkit.org/show_bug.cgi?id=80706.

r=me but please remove references to region node lists from the code/changelog.

Bonus points for removing a parseAttribute() overload. :)

Needs "using" to build on win, but you know that.

The patch was "preemptively" landed in http://trac.webkit.org/changeset/110797 by accident. Fixed the reviewer name in http://trac.webkit.org/changeset/110817.
