[Bug] Up arrow key navigates command history instead of moving cursor in multi-line prompts

Bug Description
Before I could click the up key when typing a large prompt to move between lines if I needed to edit the prompt, allowing me to navigate the text quickly. Now it appears clicking up key while wring a prompt just loads the previous commands?
