Path hover does not work when coloring by a dimension #2427

In the example below where the Path data is colored by a variable the hover tool does not correctly display the hover data for other dimensions:

coord_system = ccrs.UTM(17)

userLine = [[ 501386.89237725, 3026047.23276743],
 [ 502233.40219658, 3030363.86891928],
 [ 497065.22714886, 3031309.6654351 ],
 [ 499260.08171301, 3027147.9437062 ],
 [ 494678.08475863, 3026891.08691589],
 [ 494971.32963864, 3025188.1383645 ],
 [ 496475.86909916, 3025394.03293946],
 [ 496061.07730504, 3026116.58492655],
 [ 497530.90995815, 3026357.00292598]]

line_pd = pd.DataFrame(userLine, columns=['Longitude', 'Latitude'])
pressure = pd.DataFrame(np.arange(0,401,np.ceil(401/len(userLine))), columns=['Pressure'])
windspeed = pd.DataFrame(np.arange(0,201,np.ceil(201/len(userLine))), columns=['Max_Wind_Speed'])
alldata = pd.concat([line_pd,pressure,windspeed], axis=1)

%%opts Path (cmap='inferno') [tools=['hover'] color_index='Max_Wind_Speed']
gv.Path([alldata], vdims=['Pressure','Max_Wind_Speed'], crs=coord_system)
