Fixed

• Hints and popovers in an open <dialog> with a transform or filter
  now stay next to their element, also after the dialog reopens.
  (#627)
• Tour steps scrolled out of a visible scrollable container are now
  scrolled into view.
  (#577)
• The popover title and footer are divs instead of header and footer
  landmarks, and the centered dummy element gets no aria attributes.
