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()

Reproduire l’exemple fourni de box-trace avec width 0 et boxpoints défini sur "all", puis suivre le chemin de rendu de la légende de la boîte. Le comparer au comportement existant lorsque line alpha vaut 0 ; le travail est terminé lorsque le marqueur apparaît dans la légende alors que la boîte elle-même ne peut pas être rendue.
