steps to recreate:

type a command long command

shrink the width of the command window to shorter than the last command so that a horizontal scrollbar appears

clc

start typing another long command. any characters between the new shorter width, and the previous long command that triggered the h-scrollbar will be typing off screen until it hits the previous width, then it will wrap to the next line.  this will repeat with any additional lines until the window is made narrower (wider doesn't change anything) at which point it will start wrapping at the new smaller width.

using a backspace key after wrapping will move the window view to the cursor position at the end of the previous line, though.

Without doing the clc, it seems the gui keeps track of the new shorter width and wraps at the right spot.  I think I was at some point able to trigger the same 'typing off screen' effect without the clc, but can't recreate it at the moment.

I would expect that either the typing would wrap at the current window width, or if for some reason it can't, the view should follow the cursor so it's always on screen.
