Bug: rotated text in `guide_colourbar()`

[teunbrand]

In current main branch, when using rotated legend text with vjust = 1, the text starts overlapping the colourbar itself.
In the example below, I expected the left-most 'C' to start at the right of the colourbar.

devtools::load_all("~/packages/ggplot2/")
#> ℹ Loading ggplot2

ggplot(mpg, aes(displ, hwy)) +
  geom_point(aes(colour = cty)) +
  scale_colour_continuous(
    breaks = c(10, 20, 30),
    labels = c("A", "B\nB", "C\nC\nC")
  ) +
  theme(
    legend.text = element_text(angle = 270, vjust = 1)
  )

Same issue for guide_bins()

devtools::load_all("~/packages/ggplot2/")
#> ℹ Loading ggplot2

ggplot(mpg, aes(displ, hwy)) +
  geom_point(aes(size = cty)) +
  scale_size_continuous(
    breaks = c(10, 20, 30),
    labels = c("A", "B\nB", "C\nC\nC"),
    guide  = "bins"
  ) +
  theme(
    legend.text = element_text(angle = 270, vjust = 1)
  )
