Vue SFC style not formatted with lang attribute set to "css" #6871
Description
Prettier 1.18.2
Playground link
--parser vueInput:
<style lang="css" scoped>
p { color: #2a2A2F }
</style>Output:
<style lang="css" scoped>
p { color: #2a2A2F }
</style>
Expected behavior:
<style lang="css" scoped>
p { color: #2a2a2f }
</style>
The output is as expected if the lang attribute is set to "scss" or is removed altogether.
