{cite} in captions of markdown-figures

[a7p]

Describe the bug

context When I cite something in a caption, e.g.

:::{figure-md} bla
<img src="./logo.png">

{cite}`holdgraf_evidence_2014`
:::

and try to build a pdf (--builder=pdflatex, xelatex flavored)

expectation I expected a rendered citation to occur.

bug But instead compilation stops. Here's an error message I ran into:

$ jb build --builder pdflatex  ./tmp/
...
! Undefined control sequence.
\hyper@@link ->\let \Hy@reserved@a
                                   \relax \@ifnextchar [{\hyper@link@ }{\hyp...
l.127 ...hyperlink{cite.markdown:id3}{HdHPK14}{]}}
                                                  \label{\detokenize{intro:b...

manually editing the latex-file and adding \protect before the \hyperlink statement as suggested in https://github.com/executablebooks/jupyter-book/issues/1584#issuecomment-1006752501 solves the issue.

Reproduce the bug

add

:::{figure-md} bla
<img src="./logo.png">

{cite}`holdgraf_evidence_2014`
:::

to the example-files and run

jb build --builder pdflatex  ./
