    LibreOffice: Work around missing state-changed:focused event
    
    After (at least) leaving the Save As dialog, paragraphs claim to be
    focusable but no longer claim to be focused. As a result, we ignore
    text-related events from those paragraphs having concluded the user
    is not interacting with them. Clearing the cache for these paragraphs
    seems to get them to report the focused state when they have it. So
    it seems LibreOffice is failing to emit the state-changed event needed
    to get AT-SPI2 to update its cache.
