Steps to reproduce

1. I copied an extra closing tag and pasted it.
2. It started showing errors until deleting the extra closing tag

[jakebailey]

I think we need more of a repro than that, unfortunately

[pedro757]

@jakebailey Hope this helps.

As you can see I'm using AI suggestions but it panicked before I can accept closing tag suggestion.

              <Button
                className="mt-4 w-full"
                onClick={() => {
                  void router.push("/admin/new-sub");
                }}
              >
                Crear subscripción
// CRASHES 

I don't know if it's the same error I described above, I copied the logs anyway.

Let me know if you need anything else.

[pedro757]

@jakebailey Look at this other example, deleting a closing tag, it starts panicking everywhere.

This one is quite literally impossible:

interface conversion: ast.nodeData is *ast.Token, not *ast.Identifier goroutine 360382 [running]:

	github.com/microsoft/typescript-go/internal/ls/utilities.go:371

Because the code says:

func isThis(node *ast.Node) bool {
	switch node.Kind {
	case ast.KindThisKeyword:
		// case ast.KindThisType: TODO: GH#9267
		return true
	case ast.KindIdentifier:
		// 'this' as a parameter
		return node.Text() == "this" && node.Parent.Kind == ast.KindParameter
	default:
		return false
	}
}

And line 371 is the Text call, which is gated by KindIdentifier...

Sounds like some code somewhere is calling factory.NewToken(ast.Identifier)!
