In order to get focus memory for tabs working properly, we need a notion of whether or not the underlying Page is focused. We need this since Web pages should be able to shift around programmatic focus in background tabs and have the new focused frame and focused node be remembered if you switch back to that tab. Our current code was relying only on the window being active plus the frame being focused to decide that it should draw focus rings and blink carets. However this isn't good enough in the case described above. I have just added a new boolean to FocusController that indicates whether or not the Page is focused. The Mac and Windows ports have been patched to update the Page focused state properly (I hope). Other ports will need to call page->focusController()-
setFocused(true) or setFocused(false) now in order for everything to work properly.
