Vertex colors and tubes does not work

Questions
1

There seems to be something wrong with the VertexColors when using tubes.

dat = Table[{Cos[x], Sin[x], x/10}, {x, 0., 10}];
col = RGBColor /@ dat
{
 Graphics3D[{PointSize[Large], Point[dat, VertexColors -> col], 
   Line[dat]}],
 Graphics3D[{Thick, Line[dat, VertexColors -> col]}],
 Graphics3D[{CapForm["Square"], JoinForm["Miter"], 
   Tube[dat, VertexColors -> col]}, Lighting -> "Neutral"]
 }

This also seems to be the case in the documentation, this is an example from the VertexColors doc.

We are aware of this issue, and the fix is coming soon in the next Mathematica version upgrade.
Thank you
