Terminal extension breaks cycling through history with multiline items

Stepping through the history with the Terminal extension enabled is done with the arrow up/down keys., but when a history item spanning multiple lines is encountered, the cursor gets "trapped" in the command and the arrow keys can no longer be used for further history navigation.

This behavior is accompanied by the following traceback in the terminal that idlex is being run from:

Exception in Tkinter callback
