TUniCustomPanel collapse/expand Events do not update Collapsed property

[AlexForever]

In uniAlignmentClient mode, when doesn't exist events OnCollapse or OnExpand, property Collapsed not updated.

In our logic we rely on this property. In order for this to work, we have to make empty handlers OnCollapse/OnExpand.

Maybe there is another way or to reconsider this?

procedure TUniCustomPanel.InitCollapseEvents;
var
  sSide: Boolean;
begin
  sSide := Assigned(UniParent) and (UniParent.AlignmentControl = uniAlignmentServer);

  if sSide or Assigned(FOnCollapse) then
    JSAddEvent('collapse', ['w', '%0.getWidth()', 'h', '%0.getHeight()'], H_JSOnCollapse);

  if sSide or Assigned(FOnExpand) then
    JSAddEvent('expand', ['w', '%0.getWidth()', 'h', '%0.getHeight()'], H_JSOnCollapse);
end;

I think it's worth considering a universal mechanism for subscribing to Ajax events. Some list of all events and checkboxes on them. Whoever needs them can uncheck them so they don't come. For all components.
