Plotly Python can't do a Mesh3d animation with more than one color in a frame!

I have the following code:

import plotly.graph_objs as go

hh=3
ww=5
xx0=0
yy0=0
zz0=0

xx1=[xx0, xx0,    xx0+ww, xx0+ww, xx0,    xx0,    xx0+ww, xx0+ww]
yy1=[yy0, yy0+ww, yy0+ww, yy0,    yy0,    yy0+ww, yy0+ww, yy0]
zz1=[zz0, zz0,    zz0,    zz0,    zz0+hh, zz0+hh, zz0+hh, zz0+hh]

fr0a = go.Mesh3d(x=xx1, y=yy1, z=zz1, flatshading=True, color='red', i = [0,0], j = [1,3], k = [2,2])
fr0b = go.Mesh3d(x=xx1, y=yy1, z=zz1, flatshading=True, color='yellow', i = [3,3], j = [7,2], k = [6,6])
fr0c = go.Mesh3d(x=xx1, y=yy1, z=zz1, flatshading=True, color='green', i = [0,0], j = [3,4], k = [7,7])
fr0d = go.Mesh3d(x=xx1, y=yy1, z=zz1, flatshading=True, color='cyan', i = [2,2], j = [6,1], k = [5,5])
fr0e = go.Mesh3d(x=xx1, y=yy1, z=zz1, flatshading=True, color='gray', i = [4,4], j = [1,2], k = [2,3])

fr1 = go.Frame(data=fr0a)
fr2 = go.Frame(data=[fr0b,fr0a])
fr3 = go.Frame(data=[fr0c,fr0b,fr0a])
fr4 = go.Frame(data=[fr0d,fr0c,fr0b])
fr5 = go.Frame(data=[fr0e,fr0d,fr0c])

axis0 = dict(showbackground=False,showticklabels=False,title='')

fig = go.Figure(
    data=[fr0a],
    layout=go.Layout(
        showlegend=False,
        scene=dict(aspectmode='data',xaxis=axis0,yaxis=axis0,zaxis=axis0),
        title="the animation",
        updatemenus=[dict(
            type="buttons",
            buttons=[dict(label="Play",
                          method="animate",
                          args=[None,dict(frame=dict(duration=1000,redraw=True),fromcurrent=False)])
                     ])]
    ),
    frames=[fr1,fr2,fr3,fr4,fr5]
)
fig.write_html("theanim.html",full_html=False, include_plotlyjs='cdn')

but I can’t display the other faces with different colors in the frame list. It’s just limited to the first face in the list.
