Issue

Ever since the latest update, it seems I can't clear the terminal with command+K. This issue only happens when I have done npm start to start webpack for one of my apps. Currently, whenever I press command+K, it makes ^L appear at the bottom of the terminal.

Here is a screenshot of the issue: (You can see the ^L come everytime I try to clear at the bottom):

EDIT: Just to provide some more info, if I exit out of the process with control+C, and then run the clear with command+K it works fine.

No source file or test is named in the issue. First reproduce the behavior in Hyper on macOS while npm start is running, then use the issue discussion and repository search to locate terminal shortcut handling; done means Command+K clears the terminal without inserting ^L during the running process.
