Box trace with `boxpoints="all"` and `line_width=0` doesn't render marker in legend

When the width of a box trace is set to 0 and boxpoints is set to "all", it seems that the legend still attempts to render the box in the legend, which will never appear because the width is 0. It seems that in this case the marker should appear in the legend instead, as is already the case when the line alpha is 0.

I'd be happy to work on this as well.

import plotly.express as px

df = px.data.tips()

fig = px.strip(df, x="total_bill", y="day", color="time")
new_fig = fig.update_traces(line={"color": None, "width": 0})
new_fig.show()

Das bereitgestellte box-trace-Beispiel mit width 0 und boxpoints auf "all" reproduzieren und anschließend den Rendering-Pfad der Box-Legende nachverfolgen. Mit dem bestehenden Verhalten vergleichen, wenn line alpha 0 ist; als erledigt gilt es, wenn der Marker in der Legende erscheint, obwohl die Box selbst nicht gerendert werden kann.
