What's Wrong?

Up/down arrow no longer moves cursor within multi-line input — used to cycle history when empty, move cursor when text present, now always cycles history regardless.

What Should Happen?

Up/down arrow should cycle history when empty, move cursor when text present, NOT do anything when text is present

Error Messages/Logs

Steps to Reproduce

just type multi line prompt in the context window and use up/down arrow keys
