CXTPScrollableEdit scroller does not appear

   When changing the text of CXTPScrollableEdit during dialog initialization, the scroller does not appear.

This is because IsWindowVisible returns FALSE (parent window is invisible) after ShowWindow(SW_SHOW). 
See msdn:
https://docs.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-iswindowvisible

That is why Layout method not worked (it check IsWindowVisible) during scroll sycnhronization
