Using a slider creates jitter on an animated scattermapbox

[kdpenner]

An animated scattermapbox figure with a legend sometimes shows jitter while using a slider.

import plotly.graph_objects as go


lats = [_*0.02 for _ in range(500)]
lons = [0]*500

fig = go.Figure()
fig.add_trace(go.Scattermapbox(lat=[0], lon=[0], visible="legendonly"))
fig.add_trace(go.Scattermapbox(lat=[0], lon=[0], showlegend=False))

frames = []

for lat, lon in zip(lats, lons):
    frame = go.Frame(data=go.Scattermapbox(lat=[lat], lon=[lon]),
                     traces=[1], name=str(lat))
    frames.append(frame)

fig.update(frames=frames)

fig.layout.mapbox.center = {"lat": 5, "lon": 0}
fig.layout.mapbox.style = "open-street-map"
fig.layout.mapbox.zoom = 4


def frame_args(duration):
    template = {"frame": {"duration": duration},
                "mode": "immediate",
                "fromcurrent": True,
                "transition": {"duration": 0}}
    return template


def step_dict(frame):
    template = {"args": [[frame.name], frame_args(0)],
                "label": frame.name,
                "method": "animate"}
    return template

steps = [step_dict(f) for f in fig.frames]

sliders = [{"steps": steps}]

fig.update_layout(sliders=sliders)

fig.show()
