Specifying line type in the webR Canvas graphics device does not work

[bugzpodder]

Not sure if its discrependency is intended but i am seeing a very slight difference in the following code in RStudio vs webR

library('ggplot2')
ggplot() +
    geom_hline(aes(yintercept = 10, linetype = "p-value Threshold"), color = "green") + 
    geom_vline(aes(xintercept = 1, linetype = "Upper FC"), color = "blue") + 
    geom_vline(aes(xintercept = -1, linetype = "Lower FC"), color = "red")

RStudio shows the lines as dashed and webR (using plot()) draws the line as solid.

Thanks, this looks like a more general bug with line types in the Canvas graphics device!

For example, the code

plot(1:10, 1:10, type="l", lty=2)

should produce a dashed line, but instead produce a solid line.
