Plotting union with seriestype kwarg fails

[mforets]

The following used to work probably changed after #2653 :

L1 = LineSegment([3.3, -1.3], [3.7, -1.3])
L2 = LineSegment([3.3, 1.5], [3.7, 1.5])
L3 = LineSegment([3.3, -1.3], [3.3, 1.5])
L4 = LineSegment([3.7, -1.3], [3.7, 1.5])

U = UnionSetArray([L1, L2, L3, L4])
plot(U, color=:black, style=:dash, lw=1.5, seriestype=:solid, marker=:none, alpha=1.)

The backend must not support the series type Val{:solid}, and there isn't a series recipe defined.

Confirmed, it worked before, but simply because we used a different plot recipe. I think this is a drawback in the plotting backend. As far as I can tell, the same result can be produced by omitting seriestype=:solid, marker=:none now.

plot(U, color=:black, style=:dash, lw=1.5, alpha=1.)
