Description
I'm coming to report another bug on the go.Surface.
As the code shown below, you can easily get the bug.
The plotly go.Surface only plots the Contour_Val in rectangular shape. It completely ignores those outthrust values in the 'Contour_Val' matrix.
The Matplotlib shows the correct surface(or contour).

Matplotlib version (correct):
Plotly version (wrong):
only those values which form a regular rectangular shape in the matrix are effective in go.Surface plot:
Solution suggestion:
Either modify the go.Surface or the go.Contour to make it possible to plot the 2D contour on any plane in a 3D figure.
Hope this issue can be solved together with [#5157] soon. Thanks!
