Terminal starts at the top of the window after leaving a "screen"

• 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 10.14.2 (Mojave)
• Hyper.app version: 3.0.2
• Link of a Gist with the contents of your .hyper.js: https://gist.github.com/LeSeulArtichaut/324351ba22b27b7dbe9e50c7a1fe5359
• Relevant information from devtools (CMD+ALT+I on macOS, CTRL+SHIFT+I elsewhere): N/A (No errors in console, and didn't have time to dive into the sources)
• The issue is reproducible in vanilla Hyper.app: Is Vanilla

Issue

After leaving a screen (as a secure ssh on a distant machine) using Ctrl-A d or Ctrl-D, Hyper resumes the previous shell (normal behaviour) but writes from the top of the canvas without clearing the window, making it really difficult to read the terminal. Hyper should either draw from the bottom of the "used space", or clear the canvas.

Thanks a lot for considering the issue!

Reproduce the issue in vanilla Hyper on macOS by entering screen, detaching with Ctrl-A d or Ctrl-D, and observing the resumed shell. Trace the terminal rendering path involved after screen exits; done means the resumed shell renders at the bottom of the used space or the canvas is cleared.
