Problematic ANSI escape

[jaydenseric]

• I am on the latest Hyper.app version

• I have searched the issues of this repo and believe that this is not a duplicate

• OS version and name: MacOS Sierra v10.12.6

• Hyper.app version: 2.0.3 (canary)

• The issue is reproducible in vanilla Hyper.app: Is Vanilla

Issue

In a file called bug.js:

process.stdout.write('One\n')

// ANSI escape to clear the screen
// See https://github.com/sindresorhus/ansi-escapes/blob/v3.0.0/index.js#L77
process.stdout.write('\u001Bc')

process.stdout.write('Two\n')

Running node bug in Hyper outputs:

wo

When it should be:

Two

The Terminal app has the correct output (although it does not correctly clear the scroll history, but that's another story).

@jaydenseric Hey there, could you test this in the Visual Studio Code terminal, please? If it happens there as well, it's xtermjs/xterm.js#1395 otherwise Hyper's fault.

Tested using the latest canary build
It seems to be working properly
