Animation glitch with missing data

When having missing at the start time. Scatter markers are not being draw. When another marker has no values after a certain point in time this point "converts" to the no drawn point.

Im using plotly 4.5.0 in Python 3.7 with Anaconda.

Here is an example:

df = pd.DataFrame([
    {"time": 0, "id": "A", "x": 0, "y": 0}, # No data for B at timestep 0
    {"time": 1, "id": "A", "x": 0, "y": 1},
    {"time": 1, "id": "B", "x": 1, "y": 0},
    {"time": 2, "id": "A", "x": 0, "y": 2},
    {"time": 2, "id": "B", "x": 1, "y": 1},
    {"time": 3, "id": "B", "x": 1, "y": 2}, # No data for A at timestep 3
])

fig = px.scatter(
    data_frame=df,
    x="x", y="y",
    color="id",
    animation_frame="time",
    hover_data=df.columns,
    range_x=(-1, 3),
    range_y=(-1, 3),
)
fig.show()

Unfortunately I can't upload an animation of the "conversion".

Thanks in advance!

运行提供的 Python 3.7 和 Plotly 4.5.0 示例，并检查生成的散点动画帧。比较数据开头或结尾缺少 id 的帧，然后验证缺失的标记是否仍能得到一致处理，而不是消失或被转换。当两种缺失数据情况都能在没有报告中的问题的情况下进行动画显示时，即表示完成。
