Tengo Script Returns Multiple Matches, but they are not all flagged by Vale

[piloteris]

I am attempting to write something that will flag if the same word is used twice in the same paragraph -- an echo word. I couldn't figure out a way to do this without using a tengo script, although I am option to suggestions.

I have a script that is working and returning the matches of all of the echo words, but Vale sometimes only flags one instance of each word. In VS Code, for example, only one instance of the repeated word "Leather." is underlined, when I want all of them to be. However, "times" are all underlined.

Any ideas on how I can get this working?

Text being used to test:

It was the best of times. It was the worst of times. 

Red Leather. Yellow Leather.

Rule:

message: "Word Repeated in Paragraph"
link: https://tengolang.com
scope: paragraph
script: echo1.tengo

Tengo Script (Including print statements that show that all matches are being caught/appended):

text := import("text")
fmt := import("fmt")

document := text.to_lower(scope)
words := text.fields(document)

seen := {}

matches := []

fmt.println("document: ", document)

for word in words {


  
    if seen[word] != undefined && text.count(document, word) > 1 {
        
        match_arry := text.re_find(word, document, text.count(document, word))
        fmt.println("(match_arry)", match_arry)

        for match_group in match_arry {
            match_obj := match_group[0]  // Get the map with 'text', 'begin', 'end'
            begin := match_obj["begin"]
            end := match_obj["end"]

            matches = append(matches, {begin: begin, end: end})
	    
        }


    } else {
        seen[word] = true
    }

}

fmt.println("matches: ", matches)

Script Output with JSON vale output. This is what happens when I run it -- my debugging statments print and I get what vale is flagging, but it is only one example of each word:

> vale --output=JSON test.md
