Steps to reproduce

Create a vue file with a script tag at the top;
The script tag should have attributes: 'setup' and 'lang="ts"'
The attributes should be on the same line as the opening tag like so

<script setup lang="ts">
    function helloWorld() {
        console.log("Hello, world!");
    }
<script>

This issue does NOT occur when the opening tag is split across multiple lines like so

<script
    setup
    lang="ts">
    function helloWorld() {
        console.log("Hello, world!");
    }
</script>

What is expected?

The expected behavior is that lines will be automatically indented when expected ( after "{", etc. ).
It is also expected for the "=" key to set the selected line to it's proper indentation based off of the context.

What is actually happening?

What is really happening is on any new line create, the indent is set to that of the previously selected line. This is the fallback behavior of neovim. Indentation works properly when the opening script tag is split into multiple lines as shown earlier in this bug report. I believe (but may be wrong) that the reason for this is that vue_ls does not provide it's own indentation specification. Setting "indentexpr" to "VueIndent()" or "GetVueIndent()" seeems to make all indenting fallback to the aformentioned fallback. By default "indentexpr" is set to "HtmlIndent()".
