Break after footnote markers

[alxtsg]

Given the following piece of text extracted from a page on the Wikipedia:

Wikipedia is a multilingual online encyclopedia created and maintained as an open collaboration project[3] by a community of volunteer editors using a wiki-based editing system.[4] It is the largest and most popular general reference work on the World Wide Web,[5][6][7] and is one of the most popular websites ranked by Alexa as of October 2019.

I get the following result when using sentence-splitter to split the text:

Sentence #0: Wikipedia is a multilingual online encyclopedia created and maintained as an open collaboration project[3] by a community of volunteer editors using a wiki-based editing system.[4] It is the largest and most popular general reference work on the World Wide Web,[5][6][7] and is one of the most popular websites ranked by Alexa as of October 2019.

Does it make sense to split the text at the footnote marker [4]? The result will become:

Sentence #0: Wikipedia is a multilingual online encyclopedia created and maintained as an open collaboration project[3] by a community of volunteer editors using a wiki-based editing system.[4]
Sentence #1: It is the largest and most popular general reference work on the World Wide Web,[5][6][7] and is one of the most popular websites ranked by Alexa as of October 2019.

If this make sense, where should I start to change the codes?

Thanks for report!

Abstract text:

[Str][Punctuation][Footnote][WhiteSpace][Str][Punctuation]

We have three options.

Option 1: No Support

Sentence 0: [TEXT][Punctuation][Footnote][WhiteSpace][TEXT][Punctuation]

Option 2: Sentence 0 inlucdes Footnote( @alxtsg suggested )

Sentence 0: [TEXT][Punctuation][Footnote]
[WhiteSpace]
Sentence 1: [TEXT][Punctuation]

Option 3: put [Footnote] out of sentence

Sentence 0: [TEXT][Punctuation]
[Footnote] <- Meta Node? new Node type?
[WhiteSpace]
Sentence 1: [TEXT][Punctuation]

I agree with @alxtsg, so I select Option 2.

Because, [Footnote] depend on Sentence 0.
[Footnote] of Option 3　is not clear. (Which note for sentence 0 or sentence 1?)

Another example, remark(markdown parser) support [1] as LinkRererence node.
I think that the LinkRererence(footnote) should be included in the sentence.

(Note: TxtAST use remark internally https://textlint.github.io/astexplorer/)

Sentence 0: [TEXT][Punctuation][LinkReference(footnote)]
[WhiteSpace]
Sentence 1: [TEXT][Punctuation]

I'm ok that split the text at the footnote marker.
