Description

When in ssh, CMD+L or clear do not clear the contents. Instead the cursor jumps to the top most position as expected, but all previous contents are still visible.

I mean that´s an old issue, when is this finally going to be fixed. That issue makes Hyper unusable, as for me, I use only ssh.

Research direction
Investigate how Hyper's terminal emulation handles the clear screen escape sequence (\x1b[2J or similar). Check the xterm.js library integration and event handling. Look for any differences when Hyper is connected via SSH vs local shell.
