Why is there no less or sass emmet hint for the style tag?

• I have searched through existing issues
• I have read through docs
• I have read FAQ

Info

• Platform: Win
• Vetur version: 0.22.0
• VS Code version: 1.37.0

Problem

• The following tags are not prompted in my editor.
• It was all normal before.

template with html
template with pug
script with JavaScript
script with TypeScript
style with CSS
style with CSS (scoped)
style with scss
style with scss (scoped)
style with less
style with less (scoped)
style with sass
style with sass (scoped)
style with postcss
style with postcss (scoped)
style with stylus
style with stylus (scoped)

Reproducible Case

There is no step that can be described, that is, the auto-complete prompt of the label suddenly disappears, and it is not suitable.

The scaffold snippets have been renamed to start with either <vue>, <style>, <script> or <template>.

I’m sorry for removing the old scaffold snippets, but they are replaced by https://vuejs.github.io/vetur/snippet.html#customizable-scaffold-snippets.

• I only enabled vetur,But snippets are still duplicates
• Show only one of them is normal
