TChromium messes up the order of TForm.onActivate, TForm.onCreate and TForm.Create

[GoogleCodeExporter]

What steps will reproduce the problem:
1. Put a TChromium on a Form

What is the expected behaviour:
1. TForm.Create begins
2. TForm.Create ends
3. TForm.onCreate happens
4. TForm.onShow happens
5. TForm.onActivate happens

What do you see instead:
1. TForm.Create begins
2. TForm.onActivate happens
3. TForm.Create ends
4. TForm.onCreate happens
5. TForm.onShow happens

Environment:

I added a workaround that kinda suppresses the problem.

CEF's LoadUrl() method calls SetFocus. And if that happens before the TChromium 
control is actually visible (IsWindowVisible), the events fire in the wrong 
order.

This can be prevented by implementing the OnSetFocus event and skipping the 
default "SetFocus" by setting Handled:=True

procedure TForm1.BrowserSetFocus(Sender: TObject; const browser: ICefBrowser; 
source: TCefFocusSource; out Result: Boolean);
begin
  if not Showing then
    Result := True; // Handled, don't call "SetFocus" if the control isn't actually visible
end;
