• Moves to MutationObserver and improves catching dialog removals (while continuing to support mutation events for IE10 and below)
• Detects invalid placements of modal dialogs (within a stacking context), warning the user with console.warn, and tries to allow use anyway
• Downgrades dialogs that are moved within a page (modal => normal), matching Chrome
• Fixes an issue where focus was performed before a dialog was shown
• Fixes an issue where inner non-modal dialogs were unfocusable
