Here I cannot create something like this:

(1) TAbstract = class(TForm)
   Panel

(2) TNotSoAbstract = class(TAbstract)
   SomeButtonInsideTheInheritedPanel

Form (2) works nice.

(3) TConcrete = class(TNotSoAbstract)

Form (3) always raise exceptions saying 'Duplicate name: A component 
named "Panel" already exists'. One message for each TAbstract member. 
22-may snapshot. Known issue, or should I create a project that 
reproduces the problem and create a bug report?
