When wikipedia readers look at a reference preview, they might have a general interest in references, such as: "Which sources is this article based on?" or "This source sounds really interesting and I will need to get much deeper into the topic. Is there other literature that might be interesting to me?"
Therefore, users should have a way to directly jump to the references section when they look at a reference preview
 In the footer of the reference preview is a link that says "Jump to reference"
 If users click on the link, they jump to the reference they previewed as displayed in the references section
 Said reference is highlighted the same way it would be highlighted when clicking on the footnote indicator right now
The red border is only meant as indication of the relevant part and should not be implemented
