Web Accessibility: ARIA trees not accessible with NVDA and Firefox or Chrome

[behofer]

Steps to reproduce:

1. Get ARIA tree code example (W3C recommendation) from W3C official website: https://www.w3.org/WAI/GL/wiki/Using_ARIA_trees
2. Copy Code Example into a plain HTML file
3. Open the HTML file from step 2 in Chrome or Firefox on Windows 10 with NVDA screenreader enabled
4. Navigate the tree with NVDA screenreader in browse mode

Actual behavior:

NVDA will read the first tree element and its children (in the example "Fruits") properly whereas the following elements (example: "Vegetables") are not accessible at all/are skipped.
So, only information on the first tree element (Level 1) is passed to a screenreader.

Expected behavior:

NVDA should be able to navigate the whole tree with all its elements in Chrome.

This is reproducible in all browsers, it seems even in focus mode the navigation in the test code is broken.
