Could a top legend and top colourbar align better?

[davidhodge931]

Hi, awesome package! I was wondering if a top legend and top colourbar could align a bit better?

library(tidyverse)
library(palmerpenguins)
library(patchwork)
#> Warning: package 'patchwork' was built under R version 4.4.1
  
p1 <- penguins |> 
  ggplot() +
  geom_histogram(aes(x = flipper_length_mm, 
                     fill = species)) +
  theme(legend.position = "top") +
  theme(legend.title.position = "top")


p2 <- penguins |> 
  ggplot() +
  geom_point(aes(x = flipper_length_mm, 
                 y = body_mass_g,
                 colour = bill_length_mm)) +
  theme(legend.position = "top") +
  theme(legend.title.position = "top")

p1 + p2
#> `stat_bin()` using `bins = 30`. Pick better value with `binwidth`.
