Describe the issue:

When moving line(s) up/down they should omit folded code

Steps to reproduce the issue:

1. Write a function in the first lines of a script.
2. Fold the function definition.
3. Write some random text below the function
4. Put the cursor in the lines containing the random text.
5. Move line up/down the lines with the keyboard shortcut for Move Line Up (Alt + UpArrow)

In Positron:

In RStudio:

Expected or desired behavior:

It should go straight to the lines above the function instead of going through the function def.

Start by reproducing the issue in Positron with a folded function and the Move Line Up or Move Line Down shortcut. Trace the editor behavior for moving lines across folded ranges; done means moved lines skip folded code and go directly to the visible preceding or following lines, matching the expected behavior described in the issue.
