I think you uncovered a bug their.  Alternatively create a TCustomComponent
descendant and in the constructor add something like the following:

...
  ControlStyle := ControlStyle + [csAcceptsControls, csCaptureMouse,
    csClickEvents, csNoFocus] - [csOpaque];
...


Also, when you say "transparent", do you mean like what can be done with a
TLabel, or do you mean the whole window is truly transparent so that you
can see through it and onto the desktop?  I don't think LCL supports the
latter.
