    xwidget: Fix xwidget-at misinterpreting non-xwidget text-properties
    
    'xwidget-open' wrongly assumed the the text-property at
    min-position is an xwidget, if it exists; the fix is just
    returning nil if the text-property isn't an xwidget.
    * lisp/xwidget.el (xwidget-at): Use 'ignore-errors'.  (Bug#72848)
