ggsave error with emf and wmf "grDevices::win.metafile(...) : unused argument (bg = "white")"

[dweis-ku]

ggsave produces error when saving in wmf or emf format
Error in grDevices::win.metafile(...) : unused argument (bg = "white")

Save as PDF and PNG work as expected.

reprex:

library(tidyverse)
e <- ggplot(mpg, aes(cty, hwy))
e + geom_point()
ggsave("test.wmf")
ggsave("test.emf")

Expected that my plot would save.

Further troubleshooting:
The following code generates a wmf file successfully:

library(tidyverse)
e <- ggplot(mpg, aes(cty, hwy))
e <- e + geom_point()
win.metafile("test.wmf")
print(e)
dev.off()

I don't have Windows machine right now, but it seems this is caused by the change of #4164.

resolved in ggplot 3.3.5

Thanks for confirming!
