stdin newlines are stripped

[qexat]

bug report

description

when entering text in the stdin field, if a trailing newline is added, it will not be taken in account

steps to reproduce

run the following program with the stdin set to what is below:

program

import sys

while (char := sys.stdin.read(1)) != "\n":
    print(char)

stdin

hello world

Warning

the trailing newline must be included.

expected behavior

the program should print each character of hello world on its own line

actual behavior

the program does print each character of its own line, but then the programs hangs trying to read the standard input
