Keyboard entry after ssh broken pipe after suspend emits key codes instead of characters

[haydonryan]

Issue Description

I suspend my arch linux machine at the end of the day so that I can (somewhat) resume my work the next day. If i'm ssh'ed into a vm / server when I wake my desktop the ghostty window goes into this mode where any keypress shows (unicode?) codes

Connection to XXXXX.xxxxxx.com closed.
client_loop: send disconnect: Broken pipe

If I click onto another application then the ghostty window draws focus back to the window. I need to go to a new ghostty window (Creating new tabs and splits still works)

I'm running:

OS: Arch Linux x86_64
Kernel: Linux 6.19.8-arch1-1
Shell: bash 5.3.9
DE: COSMIC 1.0.0

Cosmic DE is in tiling mode.

Expected Behavior

I expect that it would drop the ssh session, and the keys pressed would appear as the actual character.

Actual Behavior

all key presses that are not ghostty hotkeys or OS hotkeys print codes on the screen enter still works as enter though.

the bottom command I typed ls

It's highly likely I've done something wrong here, apologies if that's the case.

Reproduction Steps

1. open ghostty
2. ssh to a remote machine
3. suspend the computer
4. wake computer
5. type ls

No response

I acknowledge that:

• I have reviewed the FAQ and confirm that my issue is NOT among them.
• I have searched the Ghostty repository (both open and closed Discussions and Issues) and confirm this is not a duplicate of an existing issue or discussion.
• I have checked the "Preview" tab on all text fields to ensure that everything looks right, and have wrapped all configuration and code in code blocks with a group of three backticks (```) on separate lines.

This is a fundamental issue with SSH that Ghostty can't fix. When you disconnect from an SSH session abnormally, the shell does not have time to reset the terminal back into a known safe state, which is why the output's all garbled (I presume you were using some TUI tool that turned on keyboard and mouse reporting, too). You need to reset the terminal via the "Reset" action in the context menu, or run the reset command which does the same thing.
