test.svg with white background instead of expected transparent background

Setting background to transparent via par(bg='transparent') seems to not trigger a transparent background of svg devices, although it works for other colors with svg devices and for other devices with transparent.

How to reproduce:

# works fine
png('test.png'); par(bg='transparent'); plot(1:10); dev.off()

# works fine too
svg('test.svg'); par(bg='blue'); plot(1:10); dev.off()

# white background added?
svg('test.svg'); par(bg='transparent'); plot(1:10); dev.off()

Workaround: stating the bg argument directly in the graphics device to transparent seems to work for all devices:

png('test.png', bg='transparent'); plot(1:10); dev.off()
svg('test.svg', bg='transparent'); plot(1:10); dev.off()

As far as I understand setting par(bg='transparent') should (but does not) work for png as well as for svg.
