Invoke margin links inside sphinx-proof blocks #94
Description
I would like to add a link in the margin of a jupyter-book, referring to text inside a sphinx-proof block, from within the sphinx-proof block. A generic example:
````{prf:example}
Text.
```{margin} Relevant reference
[link](/URL)
```
```{figure} /figure-path
:name: fig
Caption.
```
````
While the text and image render inside the example block as desired, the margin link is rendered in the margin of the sphinx-proof block instead of in the "global" book margin. A way to thus render the margin link in the "global" margin instead would be very helpful.
