OS: Darwin arm64 23.4.0

Steps to reproduce the issue:

1. Copy a multiline expression but not the entire expression
2. Paste it into the console

For example:

ggplot(
  data = penguins,
  mapping = aes(x = flipper_length_mm, y = body_mass_g)
) +

Screen.Recording.2024-06-19.at.10.36.53.AM.mov

What did you expect to happen?

The cursor should move to the end so that pressing Enter will run it and be ready to paste the next part of the expression.

Were there any error messages in the output or Developer Tools console?

none

I've addressed this issue, and several other issues I found, in #6125.

Additionally, I worked up a little spec of how paste should work here:
