Log:
FLEX-33272. RTE occurred while trying to hide columns of an AdvancedDataGrid
having lockedColumnCount greater than 0 that was scrolled all the way over to
the right.
When the columns were hidden the horizontalScrollPosition was no longer valid
and visibleColumns got out of sync with the newly updated displayableColumns.
