Testing instructions

• Prepare a playlist with multiple videos
• Test drag and drop feature in user playlists, ensure only draggable on custom sort (can be dragged back to original position
• Test drag and drop NOT working on online playlists
• Test drag and drop in BOTH list or grid view, ensure videos can only be moved by dragging the grab bar
• Test dragging video title (link) and channel link to text box like top nav still makes it filled with an URL

Thank you for picking these changes up and continuing the work on them. One thing I noticed in my testing is that it is not possible to drag a video back to the location it came from aka cancelling the move.

Because you can only drag after you have moved a mouse pointer over the video number it makes dragging on a touch screen impossible :(

You can test it on your phone using the steps mentioned here: #8621 (comment)

This is introduced to fix being able to move the item on empty area on the box
Could use some directions

Question: If you have a playlist on YouTube and switch the sorting to Manual (its called Custom on our side) it will replace the index numbers and with the grab bar. Do we want todo the same or keep the current approach?

[PikachuEXE]

Well if you want I can show grab bar always with index number (which this PR already looks like it for device without hover
I am fine with grab bar shown on hover/always, up to you guys...
