Seaborn: Can't handle more than 6 styles

[mueslo]

Plotting e.g. sns.lineplot(x="airflow", y="noise", hue="name", style="name", data=df, markers=True) with more than 6 different names gives ValueError: Thesestylelevels are missing dashes.

Expected behaviour: Marker and line style loop cyclically and their sizes have a large least common multiple so the period between recurring styles is large.

I'm closing in favor of #1513 which is a bit more general and includes a runnable example. Feel free to weigh in there.
