Juno PlotPane default behavior different between OSX/Linux and Windows


I’ve started getting more serious about testing my packages on Windows, starting with ECharts.jl. I’ve noticed that when using Juno on OSX/Linux, the plot pane automatically has a white background, which is perfect as I set a transparent background in ECharts.

Inside Windows Juno, the background matches the Juno theme, which is gray/black. This is not so good.

Is this intentional to have different settings for the background of the plotpane?
