Comments or Future Work:

• The test requires to pin two tabs, then drag first tab over the other.
• First tab can be pinned and retrieved again(DOM element references change when you pin a tab). However, the second pinned tab is having trouble retrieving again after pinning.
• This causes issues when you use the drag_and_drop /or/ drag_and_drop_by_offset method, its gives a stale element error.

I have tried making the code as 'robust' as possible while switching window handlers and using more stable tab identifiers such as tab-titles instead of tab-index to fetch and refetch tabs.

Closing this for Sangie to start fresh from test code in PR821. (which I'll also close)
