"Double click to isolate one trace" does not always do so

Double clicking on one element in the legend does not always isolate the element's corresponding trace. Sometimes all traces are shown, and sometimes no change is made. See the recording below. A double click preceded every flicker.

import plotly.graph_objects as go


fig = go.Figure()

trace1 = go.Scattermapbox(lat=[0], lon=[0])
fig.add_trace(trace1)

trace2 = go.Scattermapbox(lat=[1], lon=[1])
fig.add_trace(trace2)

lat_cen = 0
lon_cen = 0

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

fig.show()

首先运行提供的 Python 示例，并复现双击图例时不一致的行为。跟踪 Scattermapbox 图形使用的图例交互入口点；完成的标准是：双击一个图例元素后，能够始终隔离其对应的 trace，不会闪烁，也不会让所有 trace 保持可见。
