In June 2023 update of VS Code. Developers add possibility to customize CSS modules in JSX/TSX files.
But now it doesn`t work. Here my settings
"emmet.syntaxProfiles": {
"jsx, tsx": {
"markup.attributes": {
"class*": "className"
}
}
},
Also I used custom file with snippets for Emmet. Try add this rule there and try to disable snippet file. It doesn`t help
UPD. Add link the VS Code Update
