I have an RTL (Hebrew) MediaWiki 1.34.0 website in which I am having a serious problem creating footnotes for articles with the core Extension:Cite because its de-facto lack of support in Hebrew, as described in great depth here:

• Topic:Vkwgisqt5avfpxsx
• Topic:Vmaeibyd3boa6ius

Therefore, I thought of the following alternative approach;

Creating a JavaScript front end alternative to created footnotes in a similar way to that of MediaWiki Cite

It should run after enabling support in raw HTML (and after heeding associated warnings):

Manual:$wgRawHtml

The code should look approximately like this (unfinished code):

Template:Footnote

תבנית:הערה

<includeonly><span dir="rtl" class="footnote"><sup class="footnote_inner">{{{1}}}</sup></span></includeonly><noinclude>

[[קטגוריה:תבניות]]
</noinclude>

JavaScript

document.querySelectorAll(".footnote>sup").forEach((element, i) => {
    const li = document.createElement("li");
    li.append(...element.childNodes);
    element.textContent = i + 1;
    const footnotes_list = document.querySelector(".footnotes_list"); 
    footnotes_list.appendChild(li); 
});

const numbers = Array.from(Array(100)).map((e,i)=>i+1)
document.querySelectorAll(".footnote").forEach( (element, i)=>{
    element.setAttribute("href", `#footnote_${numbers[i]}`)
    element.setAttribute("id", "fn_"+numbers[i]);
});
document.querySelectorAll(".footnotes_list>li").forEach( (element, i)=>{
    element.setAttribute("id", "footnote_"+numbers[i]);
    element.setAttribute("href", `#fn_${numbers[i]}`)
});

Lets say I do create a 100% working code,

A question remains:

Is it SEO problematic to create footnotes with JavaScript (in MediaWiki websites)?

A WebMasters StackExchange topic was created:

Is it SEO problematic to create footnotes with frontend JavaScript?

I can't link but Googling the above name should lead to it.
