Reproduce the issue in Windows Terminal 1.21.2361.0 on Windows 10.0.22631.0 with Japanese IME enabled, testing both fish in WSL and PowerShell 7.4.5. Compare the input text color with the configured foreground color under the conditions shown in the attached recordings; done means the color remains fixed during Japanese input.
