[BUG] Strange behaviour of Prompt.ask

[domef]

• I've checked docs and closed issues for possible solutions.
• I can't find my issue in the FAQ.

Describe the bug

When calling Prompt.ask it will give you also the text input you type before calling it.
Example:

import time
from rich.prompt import Prompt

time.sleep(5)
prompt = Prompt.ask("Write something")
print(prompt)

For example if I type hello during the sleep and then world when asked the output is:

helloWrite something: world
helloworld

Sometimes it doesn't even wait for my actual input when asked (I can't reproduce it deterministically):

hello
Write something: hello

Are these behaviours expected?

This is an expected behavior of terminals. Any keys you press are buffered in standard input until something, like input(), reads from it.
