And for multilivel trees i am just running the SwingSet2 JTree demo and see that VoiceOver correctly handles full/partial collapse and expand - that after that there are no anomalies like VO output does not correspond to where cursor actually positioned.

Ok. I was thinking of something like when nodes are collapsed or expanded then can we log some output like Children are valid or invalid.
Otherwise I have tested the fix with swingset2 demo and the test mentioned in [JDK-8320664](https://bugs.openjdk.org/browse/JDK-8320664) which behaves fine with the fix.
