Note that AX_ATTR_KEY_SHORTCUTS may already be set above, in
GetSparseAXAttributes.

Let's skip this one if that one already set that attribute. Change this to:

if (src.KeyboardShortcut().length() &&
!dst->HasStringAttribute(ui::AX_ATTR_KEY_SHORTCUTS))

-      dst->AddStringAttribute(ui::AX_ATTR_SHORTCUT,
+      dst->AddStringAttribute(ui::AX_ATTR_KEY_SHORTCUTS,
                               src.KeyboardShortcut().Utf8());
     }
