• [yes ] I have searched through existing issues
• [yes] I have read through docs
• [yes] I have read FAQ
• [yes] I have tried restarting VS Code or running Vetur: Restart VLS

Info

• Platform: Win
• Vetur version: 0.34 and 0.34.1
• VS Code version: 1.57

Reproducible Case

I write a typescript script like this

export default class ItemCell
    extends Vue
    implements ItemController { 
}

when i used shift+alt+f to format it, it changed to a wrong format style like:

export default class ItemCell
    extends Vue
    implements ItemController 
{ 
}

the first brace went to the next line. (only happens when i use both "extends" and "implements")

this issue does not exist when i use the previous versions of vetur (<= 0.33.1)
