All indices return with threshold = 0 aren't a perfect match

[dbismut]

Is there an existing issue for this?

Description of the bug

Version 7.0 (but reproductible in 6.6.2)

It seems like when using a threshold of 0 combined with ignoreLocation to return a perfect match, as long as there is one perfect match in the searched text, all other groups of matches are returned no matter how fuzzy they are.

The Fuse.js version where this bug is happening.

7.0.0

Which version did this behavior use to work in?

Not sure

Steps To Reproduce

const list = [
{ title: 'rouge desert groue'},
]

const fuseOptions = {
  //isCaseSensitive: false,
  includeScore: true,
  shouldSort: false,
  includeMatches: true,
  findAllMatches: false,
  minMatchCharLength: 2,
  threshold: 0,
  ignoreLocation: true,
  keys: ["title"]
};

const fuse = new Fuse(list, fuseOptions);

// Change the pattern
const searchPattern = "rouge"

console.log(fuse.search(searchPattern))

Here is the returned object:

[{
  item: {
    title: "rouge desert groue"
  },
  matches: [{
  indices: [[0, 4], [9, 10], [13, 17]],
  key: "title",
  value: "rouge desert groue"
}],
  refIndex: 0,
  score: 0.01857804455091699
}]

Expected behavior

There is only one perfect matching indice — which is the first one — so only one indice should be returned:

[{
  item: {
    title: "rouge desert groue"
  },
  matches: [{
  indices: [[0, 4]], // only ONE indice should be returned
  key: "title",
  value: "rouge desert groue"
}],
  refIndex: 0,
  score: 0.01857804455091699
}]
