Incompatible return value type `type[Enum]` when returning a functional-style Enum

Bug Report
When returning a functional-style Enum class from a function with the return type type[Enum] mypy reports an error.

When the created Enum class is assigned to a variable and the variable is return, mypy does not report an error.

To Reproduce

from enum import Enum

def direct_return() -> type[Enum]:
    return Enum("direct", {"a": 0})    # error: Incompatible return value type (got "Enum", expected "type[Enum]")  [return-value]

def indirect_return() -> type[Enum]:
    indirect = Enum("indirect", {"a": 0})
    return indirect                    # no error as expected

Expected Behavior

no mypy warnings

Actual Behavior

main.py:4: error: Incompatible return value type (got "Enum", expected "type[Enum]") [return-value]

Your Environment

• Mypy version used: 1.9.0 and master on mypy-play.net
• Mypy command-line flags: mypy-play.net defaults
• Mypy configuration options from mypy.ini (and other config files): mypy-play.net defaults
• Python version used: 3.12

まず、リンクされた playground の動作を参照しながら、mypy 1.9.0 または master で direct_return と indirect_return の例を再現します。次に、機能スタイルの Enum 呼び出しが type checker でどのように推論されるかを追跡し、両方の関数が警告なしで戻ることを示す回帰テストを追加します。
