[Lazarus] TSQLQuery Scroll events

[kapibara]

I made a test app to unerstand more about TSQLQuery events. It requires 
SQLite and has one table with three records.

1) Why does the dataset scroll 6 times to open a query that has a 
resultset with three records?

2) Also, directly after opening the query, why is 
BeforeScroll/AfterScroll triggered when you click the first item in the 
DBLookupListBox? Shouldn't the dataset already be on that position and 
no scroll needed? Later, if you click an item twice, only the first time 
triggers a scroll event.

3) At query open, why does it scroll from record 1 an then immediately 
to record 3? (First and last record) and then to record 1 again, 
followed by 2, 3 and 3 again? Yes, why does it scroll from record 3 two 
times in a row? Toggle "Active Query" to true and immediately look at 
the Log window, line 4 and 5.

4) Editing and posting a name gives rise to 6 more scrolls.

Explanations whats going on are highly welcome.
