Patch method breaks the array of strings

[antoniofarina]

Hi,
consider the code below.
As you can see, altering the disableLanguages array (removing an item) the patch method breaks the disableLanguages array

NOTE

the input is a part of a longer config file but, consider that I have checked the issue on the whole file. I also tried to change the spacing between elements in the disableLanguages array (["he", "hu", "zh", "nb", "da", "ro", "fi"], ['he', 'hu', 'zh', 'nb', 'da', 'ro', 'fi'], ["he","hu","zh","nb","da","ro","fi"], ['he','hu','zh','nb','da','ro','fi'], ... and so on ) with the same result

let tomlFileContent= 'baseUrl = "https://example.com/"
languageCode = "en-us"
languageLang = "en"
title = "this is the title"
DefaultContentLanguage = "en"
disableLanguages = ["he", "hu", "zh", "nb", "da", "ro", "fi"]'

value= parse(tomlFileContent)

console.log (value.disableLanguages)
## output  [ "he", "hu", "zh", "nb", "da", "ro", "fi" ]
for (var i = 0; i < value.disableLanguages.length; i++) {
        if (value.disableLanguages[i] === 'he') {
            value.disableLanguages.splice(i, 1);
            i--;
        }
    }
console.log (value.disableLanguages)
## output  ["hu", "zh", "nb", "da", "ro", "fi"]

console.log (patch(tomlFileContent, value))
### output 
baseUrl = "https://example.com/"
languageCode = "en-us"
languageLang = "en"
title = "this is the title"
DefaultContentLanguage = "en"
disableLanguages = ["he", "hu", "zh", "nb", "da", "ro", "fi"    <---- BROKEN !!!!
