List box visible items are invalidated from the top if tab stops are used (Bug 4422)

[Raimonds Praude]

Corrected TAB stop processing: if the current tab stops values were modified,
the old items remained with the "old" tabstops, while the new items appeared
with the new ones. Corrected so that all visible items are refreshed.
