[Lazarus] Changes to bugreport #33331 completely changes long standing behaviour

[Torsten Bonde Christiansen]

Dear List.

The bug report: https://bugs.freepascal.org/view.php?id=33331

has completely changed the behavious of how TTreeview behave!

The old behaviour (sending OLD current node in OnChanging, sending 
NEW/SELECTED node in OnChange) is consistent across other components as 
well.

The bug report is closed so i cannot make an objection to this "fix".

It has created a heck loads of bug in our programs due to this change - 
can this please be reverted?!?

Kind regards,
Torsten Bonde Christiansen
