Repeated clipboard read (OSC52) popup over SSH when unfocused

[taylrfnt]

Issue Description

On a vanilla install of Ghostty, I am ssh'ing from my MacOS laptop (M4 Air) to my NixOS server. While attempting to edit some configuration files, I switched focus from Ghostty to other local window, and am observing repeated OSC52 read popups.

This only happens when neovim is open via SSH, not just my shell. I have attached a screen recording for reference. This may be an upstream issue, but I could not find any relevant neovim issues.

Expected Behavior

No clipboard read notifications when unfocused

Actual Behavior

Clipboard read popups happen every time Ghostty is unfocused and neovim is the active program over ssh

Reproduction Steps

1. Install Ghostty
2. Set ssh-terminfo in configuration options
3. SSH to Linux host, open neovim
4. Unfocus Ghostty and observe clipboard read notifications

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.

Just wanted to follow up on this and add that I was able to reproduce this with a fresh Ghostty install, no need for the ssh-terminfo config entry.

I can't manage to get the recording down to Github-acceptable file size, but the inspector shows the same thing - no key events.

I downloaded a debug build (the slow one) and these are the logs streamed. I don't see anything that immediately pops out to me.
