When using `streamtube()` to draw stream tubes from vector volume data, default colors aren't matching and the surface has no edges, when it should. ``` load wind [sx,sy,sz] = meshgrid(80,20:10:50,0:5:15); streamtube(x,y,z,u,v,w,sx,sy,sz); fig2plotly(gcf, 'offline', false); ``` Expected and generated (https://chart-studio.plotly.com/~xarico10/1025/#/) plots: <img width="519" alt="Captura de Pantalla 2021-08-05 a la(s) 4 05 56 p m" src="https://user-images.githubusercontent.com/87881895/128421168-44615e81-8f34-4636-9a42-095da1d39c32.png"> <img width="780" alt="Captura de Pantalla 2021-08-05 a la(s) 4 06 10 p m" src="https://user-images.githubusercontent.com/87881895/128421195-a0a514ba-1a62-4439-8f8e-7d1ebee6b7cd.png"> Examples on using `streamtube()` can be found on: https://www.mathworks.com/help/matlab/ref/streamtube.html
