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!

Run the provided Python 3.7 and Plotly 4.5.0 example and inspect the generated scatter animation frames. Compare frames where an id is absent at the start or end of the data, then verify that missing markers remain handled consistently rather than disappearing or converting. Done means both missing-data cases animate without the reported glitch.
