I don't think that we should mess with the preferredSize of the parent.
Is there no other/better solution to these bugs? I would guess, that it
must be something in ViewportLayout, which is responsible for resizing
and repositioning the JList (or whatever child). If you think that your
solution is correct, then maybe you could write a testcase that shows
that the JDK is behaving like this too.
