The new default include pattern is now case-sensitive, so files like Component.TSX or App.JS no longer match and won’t get builtin:react-refresh-loader applied. This is a regression from the previous /.../i behavior and can silently disable Fast Refresh in projects that use uppercase or mixed-case extensions (common on case-insensitive filesystems or legacy repos).
Useful? React with 👍 / 👎.
