Issues with testing TFindDialog and TReplaceDialog in form designer

Original Reporter info from Mantis: wp @wpam

Description:

The descendants of TCommonDialog have a component editor which allows testing the corresponding dialog at designtime when the dialog is double-clicked in the form designer. This does not work correctly for TFindDialog and TReplaceDialog:

- TFindDialog: the dialog is not centered vertically but is at the top of the screen, the title bar is even above the screen top such that only a thin stripe is available for grabbing with the mouse.

- TReplaceDialog: the dialog cannot be closed any more. In Laz trunk, the dialog is at position (0, 0), in older versions it is again at the screen top such that the title bar is no longer visible at all and the form cannot be moved to another place. The dialog is poorly designed (overlapping controls - see attached screenshot) in contrast to run time.

This description is for Windows 10. On Linux I see essentially the same issues, except for the top position of the dialog which does not reach beyond the screen top.

Steps to reproduce:

At design time, drop a TFindDialog on a form. Double-click on the component and see the bug.

Repeat with TReplaceDialog.

Additional information:

I looked at older Lazarus installations on my system: Version 1.2 was the last one on my system which was still ok. The next installation 1.4.4 already has the bug.
