Example vtk/lut.py seems broken "JS Error => No interactor found for render window with identifier: 1 JS Error => Interactor class vtkWebAssemblyOpenGLRenderWindow is not recognized! JS Error => Could not startEventLoop for 1""

Reproducing

Steps:

• Create python venv. Tested with Python 3.13.7 on my linux/firefox

  Then

python -m venv .venv
pip install "trame-vtklocal[vtk]"
python examples/vtk/lut.py
