dash 0.5.13.1: strange pipe behaviour

With dash 0.5.13.1 together with your latest patch I got this:

$:~> echo date | /bin/sh
$:\w> Do 30. Okt 12:21:36 CET 2025
$:\w>
/bin/sh: 1: Cannot set tty process group (No such process)
$:~>

with dash 0.5.12 and bash this works:

$:~> echo date | /bin/bash
Do 30. Okt 12:22:52 CET 2025
$:~>

Greetings
