Magnific popup does not work (Fixed temporarily)

[kthoden]

NB this has been temporarily fixed by explicitly adding jquery.magnific-popup.min.js to the header of the base template. It is included in the app.js, though, but doesn't seem to get loaded.

For example, https://mprl-series.mpg.de/studies/11/3/index.html#65 will just open the image, the browser console says:

Uncaught TypeError: $(...).magnificPopup is not a function
