Yea, this is a known behavior. VTK forces the window’s dimensions on the canvas. Unfortunately, there isn’t much you can do right now because this event handler is setup inside the interactor in C++ - [vtkWebAssemblyRenderWindowInteractor.cxx#L43](https://gitlab.kitware.com/vtk/vtk/-/blob/master/Rendering/UI/vtkWebAssemblyRenderWindowInteractor.cxx#L43)

VTK can provide 2 options:

1. resize the canvas to window dimensions upon browser resize (current behavior)
2. canvas ignores resize events from the browser window. (this is what you need)
