Problem

Auto indent does not work. I googled about this issue for many times, but I cannot find a solution, can't even find a discussion about this issue.

Reproducible Case

Description

I thought auto indent should work out of the box but it bothered me for long time.

Currently, I am relying on formatOnSave to correct the indentation.

Discovery

1. Atom does not have this issue. Sublime works a little bit tricky, it's auto indent is run 1 second after paste, but at least it is correct.
2. If I manually change the language mode from Vue to HTML on VSCode, auto indent works.
   
3. I guess that auto indent is implement by something like that. But I cannot find one in Vetur source code.

	languages.setLanguageConfiguration('html', {
		indentationRules: {
			increaseIndentPattern: /<(?!\?|(?:area|base|br|col|frame|hr|html|img|input|link|meta|param)\b|[^>]*\/>)([-_\.A-Za-z0-9]+)(?=\s|>)\b[^>]*>(?!.*<\/\1>)|<!--(?!.*-->)|\{[^}"']*$/,
			decreaseIndentPattern: /^\s*(<\/(?!html)[-_\.A-Za-z0-9]+\b[^>]*>|-->|\})/
		},

It would be nice if auto indent on paste would work out of the box.

Would like to know if Auto Indent by moving up and down the code belongs to feature requests?
When I switch the doc type to HTML, Javascript, CSS/SCSS, the move up and down of the code will be indented automatically. Does it a feature belongs to extension of builtin nature of vscode?

What could we help to implement or enhance Vetur?
Many thanks.

If anyone can help, we welcome any PR.
I have briefly researched this issue.
The above setting is difficult for us to use in multiple languages in one file.
