Feature Request: Show current reference link definition on hover

[michaeltlombardi]

While working in a long Markdown document that extensively uses reference links, it can sometimes be frustrating to have to navigate to the link definitions and back to your original context while authoring/editing.

Hovering on a reference link allows you to go down to the definition:

And you can use the go-to/find-all references to go back, but the UX isn't as smooth as it could be. It always requires some context switching to leave your current context, check the link, then go back.

If possible, it would be preferable to show the current definition in the hover UI and keep the option to jump to the definition if needed.
