What do we expect on this reference? hover and click

hover:
show the popup

click on it:
scroll to reference section, load the content then expand it, then scroll to the reference number?

One problem is that the reference section does not load especially if we are translating a long article. Eg: https://language-cx.wmcloud.org/index.php/Special:AutomaticTranslation?page=Tokyo&from=en&to=hi&step=translation, try expanding the संदर्भ section

If I recall correctly, the request size limits to machine translation were inherited form the external services such as google Translate that we were using in Content Translation. For services running in Wikimedia infrastructure such as MinT and Apertium we can also consider increasing those limits. It may be easier to split the list of references at the server side for their translation than doing it on each tool that consumes the machine translation.

[mediawiki/extensions/ContentTranslation@master] AX: Improve reference handling

https://gerrit.wikimedia.org/r/1131943

We've decided to skip translating references for the time being for the following reasons:

1. They are loaded at page load, and clicking on citations will not work until these are loaded. Translating a large number of references can take a while.
2. MinT is sometimes changing the id associated with the references and remove trailing numbers like -2 etc. This breaks linking between citations and references.
3. For large sections we are translating sections by breaking them up in paragraphs. References are not broken down into paragraphs but rather list item. This would require additional special handling.
4. Added by @hueitan: If the reference is from book "A" in English, but then we translate it, it becomes "B" in the target language; the reference may become wrong, although the link still the same.

When the page is loaded, we are also expanding the reference section. Clicking on a citation takes you to the associated reference.
