Exception error detected by stylelint

Hello, when I use the following stylelint configuration to format styled-components, when I write styled-components in the tsx file, as long as I write the code, the stylelint plugin of vscode will detect an exception and report an error

This is the configuration of stylelint
{
"extends": ["stylelint-config-rational-order", "stylelint-config-standard"],
"plugins": ["stylelint-order"],
"customSyntax": "postcss-styled-components"
}

This is the error message
SyntaxError: Unexpected keyword 'function'. (11:0) at instantiate (E:\GProjects\UI\node_modules\.pnpm\@babel+parser@7.21.2\node_modules\@babel\parser\lib\index.js:64:32) at constructor

When I don't use postcss-styled-components, no such error message will appear, but at the same time, I can't format styled-components

The issue is about a syntax error when using postcss-styled-components with stylelint in VS Code for styled-components in TSX files. Start by examining the custom syntax plugin's parsing logic, likely in the main source files of the repository. Reproduce the error with the given stylelint configuration and a sample TSX file containing styled-components. Check how the plugin handles the 'function' keyword in the context of styled-components. Look at existing tests to understand expected behavior and add a test case for this scenario.
