while playing with recommender widget, noticed that underscore must be loaded globally - which is weird #2074
Description
Expected Behavior
'underscore' is normally imported by modules
Actual Behavior
https://github.com/adsabs/bumblebee/blob/master/src/js/widgets/facet/widget.js has no such import
yet _.debounce() calls probably succeed
Suggests '_' is a global variable. Which it (normally) shouldn't be (conflicts)
