TPanel.ParentBackground setzt sich - irgendwann - zurück (?)

[Sir Rufo]

Liegt wohl hier dran

Delphi-Quellcode:

{ TCustomPanel }

constructor TCustomPanel.Create(AOwner: TComponent);
begin
  inherited Create(AOwner);
  ControlStyle := [csAcceptsControls, csCaptureMouse, csClickEvents,
    csSetCaption, csOpaque, csDoubleClicks, csReplicatable, csPannable, csGestures];
  { When themes are on in an application default to making
    TCustomPanel's paint with their ParentBackground }
  if StyleServices.Enabled then
    ControlStyle := ControlStyle + [csParentBackground] - [csOpaque];
  [...]
