Describe the issue:

As reported by @thomasp85

If you send a multiline statement to the console that takes up more space than the console occupies you can suddenly no longer scroll. For example: copy-pasting a very long and complicated ggplot definition into the console

Steps to reproduce the issue:

Shrink the console down vertically into a relatively "short" area, and then paste in a long chunk of code. This breaks scrolling on the console area, however you can work around it by scrolling with the mouse wheel on the scrollbar area

# Libraries
library(ggplot2)

# example ggplot2
p2 <- ggplot(
  
  # diamonds dataset
  data=diamonds, 
  
  # split by price and cut
  aes(
    x = price, 
    group=cut, 
    fill=cut
  )
  ) +
    geom_density(

      # adjust and transparency
      adjust=1.5, 
      alpha=.4
    ) +
    theme_minimal() +
  labs(

    # set a bunch of labels
    x = "Price",
    y = "Density",
    title = "Diamonds",
    subtitle = "by Cut",
    caption = "diamonds dataset"
  ) +
  geom_hline(

    # custom x-axis
    yintercept = 0,
    color = "black",
    linewidth = 1
  )

p2

Expected or desired behavior:

Should be able to scroll on long code blocks in the console

Were there any error messages in the UI, Output panel, or Developer Tools console?

Start by reproducing the issue in the console area: shrink it vertically, paste the provided long R example, and test scrolling both in the console and on the scrollbar. Trace the console's scroll handling for long pasted multiline input. Done means long code blocks remain scrollable through the console area without requiring the scrollbar.
