Jumping around in viewport in long tables

Using latest from git: with wxwidgets 2.9.3.

I previously reported mixed results regarding the issue of the viewport
losing focus in long tables. Specifically, viewing all data in a long
table, select a field for editing, and the record being edited
disappears from the viewport.

I think I may have more of a pattern.

1. open the table for editing
2. drag the vertical slider to somewhere in the middle of the dataset
3. attempt to edit a record by double click in field/column
4. focus (place in the table) remains on the correct record
5. *without moving the vertical slider*, select a different record in
the viewport for editing, focus remains on the correct record
6. now use the vertical slider (or up/down arrows) to change to a
different place in the table
7. select a record for editing, focus (place in the table) is lost.
8. close window, reopen, use slider to go to the same position as in 6,
focus remains correct until vertical slider moved the second time.

Perhaps a variable initialization issue? The first time I move the
vertical slider it knows where it was, at the beginning. But on second
slide it either does not know where it was or where the new location is.

You can move around in the table viewing data using the slider without
problem. The issue only starts once you go into editing mode on a column.

Workaround is simple, use filtered records or just close/reopen the
editing window and just use the vertical slider once.
