Tree Node Drag & Drop Keyboard Support

[nitrogenous]

I faced an issue when the Tree items became draggable, the keyboard keys were not working well (up, down, left, right, space, enter) Can anyone no why? is it something that I'm doing wrong? I see it's either not working in the website example (primereact.org/tree/#dragdrop)

For some reason focus appear on droppoint element, I've seen that primeang DragDrop Tree works well, it's worth taking a look at their codebase. I want to fix this
