The reason behind it is that the `getAccessibleChildrenCount` API is called on the old `accessibleContext` object which return the children count as 0. Whenever we switch the page the children count is recalculated based on the root element but the `accessibleContext `object used to retrieve the child remains unchanged and due to that it return the children count 0.
