Bug summary

in the class LineCollection, the argument linestyle has no effect neither if set directly or if set afterwards with set_linestyle or with set(linestyle='--')
set_color does work. maybe its just linestyle that doesnt.

Code for reproduction

coord_start = np.column_stack((x_midpts[:-1], y_midpts[:-1]))[:, np.newaxis, :]
coord_mid = np.column_stack((x, y))[:, np.newaxis, :]
coord_end = np.column_stack((x_midpts[1:], y_midpts[1:]))[:, np.newaxis, :]
segments = np.concatenate((coord_start, coord_mid, coord_end), axis=1)

lc = LineCollection(segments, **default_kwargs)
#lc.set_array(values)  # set the colors of each segment
#lc.set_linestyle(':')
#lc.set_color(c)
lc.set(color=c, linestyle='--')

Actual outcome

linestyle doesnt change

Expected outcome

linestyle should change to the type i gave as input
