annotation_logticks not synched with minor grid line breaks

a <- ggplot(msleep, aes(bodywt, brainwt)) +
 geom_point(na.rm = TRUE) +

   breaks = scales::trans_breaks("log10", function(x) 10^x),
   labels = scales::trans_format("log10", scales::math_format(10^.x))

a+annotation_logticks()+theme(panel.grid.minor = element_line(colour='black'))

I think that's right - the minor breaks are evenly spaced between the major breaks.

[yonicd]

Shouldn't the log ticks also have minor grids connected to them?

[hadley]

No, they're completely independent.
