Split construct into bits that depend on showing the window and not

This fixes a horrific a11y problem where Show triggers callbacks
to virtual methods, while the object is not fully constructed,
which means, that the *baseclass* virtual method is called,
not the *derived* virtual method that constructs the a11y wrapper

enable a11y, and run the smoketest with dbg-util before touching
this stuff
