Describe the issue:

After executing the R code, only one plot can be displayed in the Plots panel, whenever using the base package or ggplot package.

Steps to reproduce the issue:

1. Create a new R document ( or qmd file) .
2. Generate two plots (using ggplot or base package)
3. Use Ctrl+Enter to execute the code.

library(ggplot2)
x <- rnorm(100)
y <- rnorm(100)

ggplot(data = data.frame(x, y), aes(x = x, y = y)) +
  geom_point() +
  ggtitle("test1")

x <- rnorm(100, mean = 5)
y <- rnorm(100, mean = 5)
ggplot(data = data.frame(x, y), aes(x = x, y = y)) +
  geom_point() +
  ggtitle("test2")

Expected or desired behavior:

In the Plots panel, the two generated images should be displayed.

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

NO.

Can you say more about what you are seeing? When I execute this code, I generate two plots that I can click back and forth between in the "film strip", like this:

This is the situation with the plot output when I run this piece of code. When I run these two image generation codes separately, the images can be displayed in the Plots panel. However, after executing all the code at once, only one image can be displayed.

Ah, I understand now; thanks!

This looks very related to #3915 but I am not sure it is exactly the same, so let's keep this issue open to look into this case as well.
