Certain patches were necessary to ensure AJAX functionality in all scenarios in 2.0.6 as well (some of that code has been merged into 3.x, great!) - for us we wound up using #183 from here:
https://www.drupal.org/project/facets/issues/3052574#comment-15155405 🐛 Facets with AJAX not working in most of situations Needs review
🇩🇰Denmark Worries
Patch in #183 works for us to AJAXify everything for a facet regardless of where it's placed.
Patches #184 and onward will work with AJAX for list of links or checkboxes, but doesn't work for range sliders specifically, it triggers a page refresh.
