Ajax Facets do not support Range Slider

Rerolled patch from #28 for version 2.0.6.
I did not include any changes from #33, #34, #35 as it seemed to be related to some other bug and not relevant here.
Thank you.

This works great to make the slider ajaxify.

Sorry for the noise, I was testing patches and found out that ✨ Robustify how ajax finds the facet block Needs review is already fixing this one, so I would suggest to deprecate this patch in favor of the linked one, as it covers more ground.
