Reviewed by Tyler Wilcock.

* Source/WebCore/accessibility/AXObjectCache.cpp:
(WebCore::AXObjectCache::getOrCreateIsolatedTree):
Moved the call to scheduleObjectRegionsUpdate before the creation of the isolated tree so that the relative frame can be cached in the isolated objects that are about to be created.

(WebCore::AXObjectCache::buildIsolatedTree):
Fixed the notifications sent after the whole isolated tree is built.

* Source/WebCore/accessibility/isolatedtree/AXIsolatedTree.cpp:
(WebCore::AXIsolatedTree::createEmptyContent):
Set the initial focused object in the newly created empty isolated tree to the WebArea.
