This happens because AccessibilityImageMapLink subclasses AccessibilityMockObject. This class _should_ subclass AccessibilityNodeObject, which would inherently ensure we only ever create one instance per area element, and clean it up when the area element is destroyed. The reason this was made to be an AccessibilityMockObject is because area elements do not generate renderers, which was troublesome considering we used to build the accessibility tree by walking the render tree. However, after https://bugs.webkit.org/show_bug.cgi?id=281749, we walk the DOM to build the accessibility tree, so this is now easily solvable.
