load_dotenv() does not load multiline variables correctly

[francescoVaglienti]

Given a .env such as

TEST="This is missing
no values"

and the following code

import os

from dotenv import dotenv_values, load_dotenv

load_dotenv()
config = dotenv_values()

print("--------------------")
print(config["TEST"])
print("--------------------")
print(os.environ["TEST"])
print("--------------------")

print(os.environ["TEST"] == config["TEST"])

returns

--------------------
This is missing
no values
--------------------
"This is missing
--------------------
False

This is on python-dotenv 1.0.1 using Python 3.10.14

Expected output would be

--------------------
This is missing
no values
--------------------
This is missing
no values
--------------------
True

Have reproduced this using 1.0.1 and python 3.12.
