[bug] Fallback mode includes cloned element in toArray

[juniwalk]

Describe the bug

I am using toArray() method in onStart and in onSort to calculate difference in positions. However on my phone (in fallback mode) it was giving me larger array from onStart then onSort.

To me it looks like toArray() is including cloned element from fallback mode.

To Reproduce
Steps to reproduce the behavior:

• Create sortable list with data-id attributes
• Force fallback to be enabled
• Log toArray on onStart and onSort
• See that log from onStart has more elements

Expected behavior

I think cloned element should not have the [data-id] attribute so it would not be in the toArray

Information

Versions - Look in your package.json for this information:
sortablejs = ^1.15.6
@types/sortablejs = not used
