3.23.91 - 27 February 2017

Web:

 * Add structural navigation commands to move to start, end of current
   container.

 * Handle bogus/duplicate accessible-application instances we're seeing
   with Gecko apps built against Gtk+ 3 (eliminates double-presentation
   during caret-navigation).

 * Try to prevent SeaMonkey Mail composition from unexpectedly entering
   browse mode.

 * Fix issues getting stuck in visually-hidden MathML content (MathJax).

 * Prevent generation of unrelated labels for web content (performance).

 * Fix several issues to improve our workarounds for bugs in Gecko's
   accessible-text interface.

 * More work on recovery from zombified elements (improves reliability).

 * Improve reliability of "sticky" browse mode.

 * Fix minor issues in new context-presentation support.

 * Don't present loading messages if document is neither showing nor
   visible.

MATE:

 * Work around MATE Panel's less-than-ideal event ordering and missing
   events in order to improve presentation of its Applications menu.

 * Sanity-check windows which claim to be active and ignore bogus
   window:active events and state-changed:active events from frames.

General:

 * Don't present new ancestors of menu bars.

 * Don't use the pyatspi cache for descriptions to ensure we don't
   present stale information.

 * Don't treat insertions as auto-text events if the source is no longer
   focused.

 * Fix recent (unstable-version) regression in which labels which
   label other labels stopped being presented.

 * Update the active window and conditionally present mouse-triggered
   focus changes.
