Describe the bug and the steps to reproduce it

Calling row.getParentRow() inside a custom filter function for a given column throws an error (Cannot read properties of undefined (reading 'rows')) when using the expanded and filter row models.

I faced this issue when using a custom filter function that filters by both parent and child rows, allowing for multiple levels of nesting in the data staying visible if at least one item in the "family" matches the filter.

This issue does not happen when the initial filter value is empty, only when there's a defined initial filter value (see sandbox).

After hours of investigating I hit a dead end. From what I can see, one of the row models in the waterfall of row models called through filtering is unexpectedly returning undefined, but I couldn't make sense of why. My hunch is that it's the getPreSortedRowModel() call that causes the issue, but I've seen it fail at other row model calls as well.
