Multi-language documents don't benefit from navigation by tree-sitter

[vv3rd]

Summary

In documents with multiple languages such as vue, svelte or html files, contents of <script> or <style> represented by a single node (most often raw_text).

Here's example of what I see when calling :tree-sitter-subtree command (I deleted <template> contents so that whole subtree is visible, but everything inside template seems to work as it should):

Similar story with template function invocations in javascript, in places where additional syntax highlighting is supported (to show that it's not just vue issue)

Reproduction Steps

I tried this:

1. hx [any vue, svelte or html file]
2. Start using unimpaired-style navigation or Syntax-tree Motions in script or style sections

I expected this to happen:

Navigation works just as in javascript/css files

Instead, this happened:

Unimpaired-style motions have no effect, A-left or A-right takes me to a sibling tag as opposed to a javascript textobject

Helix log

True, seems to be the same issue. Is it on a roadmap? I probably can't do it myself.
