MIssing axis when breaks = NULL

[venpopov]

This is a repeat of #2983. When breaks = NULL in scale_*, the axis disappears altogether, although I expect the line to remain. #2983 was solved back then by #3257, but now the same incorrect behavior happens.

library(dplyr)
library(ggplot2)
data.frame(x = rnorm(100), y = rnorm(100)) %>% 
  ggplot(aes(x,y)) +
  geom_point() +
  scale_x_continuous(breaks = NULL) +
  theme_classic()
