PyPlot graph is too big for plots Pane

I’m trying different features of different backends with the next simple code:

x = 1:10; y = rand(10, 2)
plot(x, y, title = "Using PyPlot",framestyle=:box)

with gr() or plotly(), the graph always fits the size of the “Plots” pane, but when I use pyplot(), the graph is just too big.1

Is this normal behavior of the PyPlot backend? Thanks in advance.
