slice() not working correctly

[xarico10]

When using slice() to draw slices for the volumetric data, an incorrect background color is placed and parts of the plot are missing.

[X,Y,Z] = meshgrid(-2:.2:2);
V = X.*exp(-X.^2-Y.^2-Z.^2);

xslice = [-1.2,0.8,2];   
yslice = [];
zslice = 0;
slice(X,Y,Z,V,xslice,yslice,zslice)

fig2plotly(gcf, 'offline', false);

Expected and generated (https://chart-studio.plotly.com/~xarico10/1041/#/) plot:

Also, there's not grid on Plotly's figure.
