Sortable might not be detecting if it uses fallback, try forceFallback: true in the options.

I have a lot of issues with Firefox and responsive mode in the past. It might just be because it's Firefox. Chrome has much better responsive mode and it always works with sortable.

This is only an issue if it doesn't work in production on mobile firefox browsers. Is this the case?

SortableJS does appear to break on production for mobile firefox browsers. @waynevanson

Edit: This appears to be a separate issue from what I'm experiencing. Dragging technically works, it's just that the page scrolling with the element makes it impossible to use.

Edit 2: I just experienced this issue while trying to debug the other issue I'm running into. Looks like the intermittent failure for dragging to work in general is also still an issue.
