Bug Report: go.Surface doesn't show the outthrust value!

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!

まず、NaN でマスクされた surfacecolor 値に対する go.Surface の動作を調べ、go.Contour のエントリーポイントと比較します。提示された X、Y、Contour_Val の例を再現し、その後、矩形の非 NaN 領域を必要とせずに outthrust 値が平面上にレンダリングされることを確認します。
