AX: In isolated tree mode, an image keeps a stale name when its figure gains
or loses flow content

Reviewed by Chris Fleizach.
Per html-aam (w3c/aria#2224), an <img> with neither alt nor title derives its
accessible
name from an ancestor <figure>'s <figcaption>, but only while that figure holds
no other
flow content. This accessible name is stored in AXProperty::{AccessibilityText,
Description},
which wasn't updated the figure subtree changed. This is now fixed.
