Windows Terminal version

1.19.10573.0

Windows build number

10.0.22631.0

Other Software

WSL Ubuntu-22.04
fish shell 3.3.1

Steps to reproduce

  1. open windows terminal and launch WSL Ubuntu-22.04.
  2. fish shell is launched.
  3. input some long command such as "echo 11111111111111111111111111111111111111111111111111111111111111111111111111111111111" so the command wraps.
  4. use the mouse to select the command.
  5. hit "ctrl+shift+c" to copy the selected command.
  6. paste it into any editor to see the result.

Expected Behavior

The command is pasted correctly including no line break.

Actual Behavior

Line breaks are inserted at the wrap points.

I tested on bash command, colored bash output, fish command and colored fish command to find that this bug only shows when I am using fish-shell and the copied content is a command. I am also posting the issue to fish-shell.

This issue is not an issue of Windows Terminal but of fish-shell. Fish shell treats its output differently from bash. https://github.com/fish-shell/fish-shell/issues/10384
This conflict between fish-shell feature and select-and-copy with mouse seems unsolvable.
I am going to turn to some other shell to run away from problem.

I find that it's okay when I use the fish shell in a remote linux server, and it doesn't work well on my WSL. I am going to trial more to locate the problem.
