Why does ggplot not allow suppressing of messages generated by its geoms?

Line at the top of a ridgeline density plot is cut off

Why is the top of the plot cut off and how do I fix this? I've increased the margins and it made no difference. See the curve for year 1854, at the very top of the left hump. It appears the line is thinner at the top of the hump. For me, changing…
