Issue with zooming when projection is set to orthographic

[aplowman]

Using the following code in a Jupyter notebook:

from plotly import __version__
from plotly import graph_objs as go

print('version: ', __version__)

data = [
    {
        'type': 'scatter3d',
        'x': [0, 1, 2],
        'y': [0, 1, 2],
        'z': [0, 1, 2],
    },
]

layout = {
    'scene': {
        'camera': {
            'projection': {
                'type': 'orthographic',
            }
        }
    },
}

fw = go.FigureWidget(data=data, layout=layout)
fw

version: 3.7.1

The resulting FigureWidget does not seem to zoom properly, as can be seen in the below GIF. When projection is set to perspective, there is no problem with zooming.

EDIT: to be more specific, it seems like when using orthographic projection, we can't zoom out from the original camera position. See the below GIF, where I start with perspective projection (where I can zoom out) and then switch to orthographic projection (where I can't zoom out beyond the original level). It could be possible I am misunderstanding something about orthographic projection however.

I think this was reported and fixed upstream, in the Javascript backend, a few weeks ago and the changes have just now made their way downstream, in plotly 3.8.0.

Thanks @marcotama. @aplowman can you confirm whether the upgrade to 3.8.0 takes care of the issue for you?

[aplowman]

Yes, verion 3.8.0 has done the trick! Thanks both.

can this issue be closed? I think so

[aplowman]

Yes.
