调研方向
Start by running the provided reproduction script inside a VSCode devcontainer, then trace Context.run with in_stream=True and pty=True/False, including the interaction with Python's input() and getpass(). Done means username and password entry work correctly without the first character being swallowed or the password prompt becoming unresponsive.

描述
While I found several different issues where something related to stdin did or does not work - this one does not seem to be covered, yet:
What happens:
Entering user name/pw from stdin to programm started with c.run does not work. What (mostly) happens:
- First character gets swallowed somehow. Have to press the first character twice. Found some issues about that one. And: Looks ike
in_stream=Falsemakes the first character appear on the first key press. - PW entry not working: When running inside the devcontainer, after pressing enter to confirm the user name, the password prompt is missing, and nothing happens when I press any key.
pty=True/Falsedoes not seem to have an effectin_stream=Falsewill avoid the 'first-character-gets-swallowed` problem, but still not fix the passwort-entry-problem
You should be able to use the following script to reproduce the issue - when executed from within a devcontainer in VSCode:
import shlex
import sys
import textwrap
from invoke import Context
INNER_SCRIPT = textwrap.dedent(
"""
from getpass import getpass
print('=== Please enter your USERNAME ===', flush=True)
username = input()
print('=== Please enter your PASSWORD ===', flush=True)
password = getpass('')
print(f'You entered username: {username}')
print(f'You entered password: {password}')
"""
).strip()
print(">>> running via invoke Context.run(pty=True)")
cmd = f"{shlex.quote(sys.executable)} -c {shlex.quote(INNER_SCRIPT)}"
Context().run(cmd, in_stream=True)
