So focusing elements on their shadow-root might cause an undesired behavior. I'm investigating. - We might have some control mechanism by which shadow host can choose whether only shadow host can be a target of tab traversal or not. Some shadow host elements might dislike that elements on their shadow root can be automatically tab traversable. shadow-hosts can set 'tabindex=-1' to focusable elements in the shadow root if they want. But that might be annoying..? 412688 3 dglazkov 2011-05-31 09:13:54 -0700 Moving of the methods can be a simple refactoring patch in itself. 413199 4 hayato 2011-06-01 00:43:47 -0700 Yeah, I posted a patch, containing only refactoring, in another bug 61839.

I was not aware of it. It seems that all tests in fast/dom/shadow are already skipped in Win. http://trac.webkit.org/changeset/84533 >> Source/WebCore/page/FocusController.cpp:341 >> +Node* FocusController::deepFocusableNode(FocusDirection direction, Node* node, KeyboardEvent* event) > > I am not sure why you moved this code. It's hard to see the diff (if any) between new and old code. I guess I moved the function to this position only because that depends on static shadowRoot and isTreeScopeOwner functions. Okay. Instead of moving this code, I decided to keep this function in original position. Instead, I moved two static functions above this function because these static functions are much smaller. But, the diff still doesn't look nice in trac.. Sad.. >> Source/WebCore/page/FocusController.cpp:430 >> + startingTabIndex = (start && start->tabIndex()) ? start->tabIndex() : SHRT_MAX; > > Why did you change this? Thank you. That's unintentional. It seemed that I wrongly 3-way merged. I reverted this change. 417276 9 96389 dglazkov 2011-06-08 09:11:52 -0700 Comment on attachment 96389 Patch View in context: https://bugs.webkit.org/attachment.cgi?id=96389&action=review > Source/WebCore/page/FocusController.cpp:174 > + // FIXME: Some elements (e.g. HTMLInputElement and HTMLTextAreaElement) do extra work in their focus() methods.

I'll address the comments and land this patch after bug 61413 is landed. Without the patch of bug 61413, we leak an element of shadow root.
