docker compose build Causes a Hang in the Docker CLI on Ghostty only

[playdohface]

Issue Description

When running docker compose build on a specific project, the process hangs immediately (and indefinitely). It works fine on other terminals (I've tried with Alacritty and Wezterm).

Expected Behavior

docker compose should run normally and show the progress.

Actual Behavior

the process hangs indefinitely. When I send SIGINT once, I get the first line of output ([+] Building 0.0s (0/0)) and the process continues hanging, when I send SIGINT again the process stops.

Reproduction Steps

Unfortunately I haven't found any way to reproduce the issue that I am at liberty to share (the project in question is proprietary). The problem could also be with docker, but only occurs in ghostty (and only since upgrading to 1.2 as far as I can say) which is why I am reporting it here.
I've taken a snapshot of the docker compose process in the hanging state:

I realize that this report might be of limited usefulness without clear reproduction steps, I'm available for further triage if necessary.
