Hover issue in subplots when adding parallel coordinates

[ZorrRRo]

When using combined subplot the hover for "xy" and "polar" charts does not work when combining those types with a parallel coordinates chart. The "scene" chart type is not affected. If commenting the par. coord. and uncomenting the pie chart, it works... Python 2.7, plotly 4.1.1.

from plotly.subplots import make_subplots import plotly.graph_objects as go

fig = make_subplots( rows=2, cols=2, specs=[[{"type": "xy"}, {"type": "polar"}], [{"type": "domain"}, {"type": "scene"}]], )

fig.add_trace(go.Bar(y=[2, 3, 1]), row=1, col=1)

fig.add_trace(go.Barpolar(theta=[0, 45, 90], r=[2, 3, 1]), row=1, col=2)

fig.add_trace(go.Parcoords(dimensions = list([ dict(label = 'x', values = [1,2,-1]), dict(label = 'y', values = [1,-2,1]), dict(label = 'f_1(x,y)', values = [-1,2,1]), dict(label = 'f_2(x,y)', values = [-1,-2,1])]) ), row=2, col=1)

fig.add_trace(go.Pie(values=[2, 3, 1]),

row=2, col=1)

fig.add_trace(go.Scatter3d(x=[2, 3, 1], y=[0, 0, 0], z=[0.5, 1, 2], mode="lines"), row=2, col=2)

fig.update_layout(height=700, showlegend=False)

fig.show()

Is there any solution for this issue ?
