How to preserve quote style when mutating field?

This is the same as https://github.com/sdispater/tomlkit/issues/112 , but I reproduced the issue using the current release (0.12.3). Not sure if it's a bug or if there's an option I don't know about.

Given this code:

import tomlkit
from pathlib import Path

path = Path("data.toml")

path.write_text("""
[foo]
bar = 'baz'
""")

data = tomlkit.parse(path.read_text(encoding="utf-8"))
data["foo"]["bar"] = "quux"
path.write_bytes(tomlkit.dumps(data).encode("utf-8"))

print(path.read_text(encoding="utf-8"))

Output:

[foo]
bar = "quux"

Is it possible to preserve the single quotes when mutating the field?

Start with the provided Python reproduction using tomlkit 0.12.3 and inspect how parsed string values are serialized after mutation. Confirm the behavior against the shown data.toml input and define done as preserving the original single-quote style when bar is changed and written back.
