jsroot from pip install root not working in notebooks (no TWebCanvas?) #20472

Description
Just reporting here that the pip install version of root in a jupyter notebook (e.g. google colab) the default drawing fails (just create any drawable object and try to draw the canvas):
309 if TWebCanvasAvailable():
--> 310 return ROOT.TWebCanvas.CreateCanvasJSON(canvas, 23, True)
311
312 # Add extra primitives to canvas with custom colors, palette, gStyle
AttributeError: <class cppyy.gbl.TWebCanvas at 0x3d259af0> has no attribute 'CreateCanvasJSON'. Full details:
type object 'TWebCanvas' has no attribute 'CreateCanvasJSON'
'TWebCanvas::CreateCanvasJSON' is not a known C++ class
'CreateCanvasJSON' is not a known C++ template
'CreateCanvasJSON' is not a known C++ enum
I note that the following is True:
hasattr(ROOT, "TWebCanvas")
But ROOT.TWebCanvas is just a cppyy shell object. Has the pythonization here incorrectly determined that class as being part of the build?
Anyway ... temporary workaround is to disable jsroot %jsroot off)
Reproducer
!pip install root
import ROOT
c = ROOT.TCanvas()
c.Draw()
in a notebook
ROOT version
6.37.01
Installation method
