Exception opening nested list after scrolling in parent list

[Cornelius Moucha]

Hello together,

I'm using the ListView component and want to combine the enableVirtualization feature with the Nested List from your demo examples.

In principle it is working good, but there is a situation, where reproducible an exception is thrown:

- Open the page

- the initial list elements work good and entering the child elements in the nested list works as expected

- scroll down (not necessarily very much)

- then an exception is thrown when entering a list element

Even when I open the child entries of a list element, which works good before scrolling, this very element throws an exception after scrolling.

Did I misinterpret something or have I overseen some necessary configuration ?

I prepared a small demo project in addition to a screen recording showing the exception.

Thank you very much in advance !

Kind regards,

cornelius
