`STDIN` is always corrupted in `com.termux.nix/files/home/.nix-profile/bin/pwsh`, and solely when `Start-Transcript` is active, in `org.kde.konsole.flatpakref`.

Prerequisites

• Write a descriptive title.
• Make sure you are able to repro it on the latest released version
• Search the existing issues.
• Refer to the FAQ.
• Refer to Differences between Windows PowerShell 5.1 and PowerShell.

Steps to reproduce

1. #!/usr/bin/env sh
   sudo dnf --verbose --debugsolver install powershell-preview
   

2. #!/usr/bin/env pwsh
   sudo dnf --verbose --debugsolver install flatpak
   flatpak -vv --ostree-verbose remote-add --installation=default --if-not-exists 'flathub' --from 'https://flathub.org/repo/flathub.flatpakrepo'
   flatpak -vv --ostree-verbose install    --installation=default --or-update     'flathub' 'runtime/org.kde.Sdk//5.15-21.08'
   flatpak -vv --ostree-verbose remote-add --installation=default --if-not-exists 'kdeapps' --from 'https://distribute.kde.org/kdeapps.flatpakrepo'
   flatpak -vv --ostree-verbose install    --installation=default --or-update     'kdeapps' 'app/org.kde.konsole//master'`
   flatpak -vv --ostree-verbose run        --installation=default --log-system-bus --log-session-bus --runtime='org.kde.Sdk' 'app/org.kde.konsole//master'

No response

Reproduce the issue in the reported pwsh environment, focusing on Start-Transcript with the Konsole Flatpak setup and the duplicated STDIN shown in the transcript. The report names no source file or test; done means interactive input remains uncorrupted while transcription is active and commands produce their normal output.
