Because of the liberal use of window.document calls throughout IPython notebook calls, using window.open and trying to draw widgets into them is basically impossible.
Thus, to achieve a presentation/presenter view (or man-behind-the curtain) of data driven widgets, a slightly more tortuous approach is needed

from ipywidgets import widgets as W
import traitlets as T
from IPython.display import display as show
from ipylayoutwidgets import widgets as DW

full = DW.FullscreenBox()

full.children = [W.Button(description="Click Me!")]
