Fix Talkback annoucement for Media Output panel.
The sound panel and media panel are using the same window, so when it
transit from the sound panel to media panel, no window-change event will
be sent. Therefore, Talkback won't be able to re-focus the panel header
which lead to the lack of the announcement.
Fix this by adding setAccessibilityPanelTitle() to trigger Talkback.
