My Featherlight galleries could include images or iframe videos (such as Vimeo), even mixed types, however if there is a video in the gallery, there are no Prev or Next buttons.

Not sure why StackOverflow is requiring code in the question when there is a jsFiddle link, but since that is the case
const $panels = jQuery('.gallery-collection');
$panels.each(function(){
const $panel = jQuery(this);
$panel.featherlightGallery({
variant: 'gal',
filter: 'a'
});
});
First tried the declarative approach, then when there were problems I switched to featherlightGallery() but no difference with regards to navigation.
