Batch processing fields doesn't go to the category

[uglyeoin]

Steps to reproduce the issue

Try to batch copy or move a field. You can copy to the same category or another. It will arrive without a category.
Try to batch move a field. It will arrive without a category.

Expected result

Batch copy copies everything about the field (and appends a number).
Batch move moves the field.

In both cases whichever category you pick should be the category that the field gets.

Actual result

No category assigned

Batch move - works as expected

Batch copy - confirm that the category is lost

Well on my video you can see that I tried to move it and it didn't work. Ah I see. It's not to do with category at all. In both cases it's to do with the group, not the category. There is no batch move category on fields! So I guess that's doing what it's supposed to, but not what I expected. And certainly not what I would call a copy. Also different to articles, which is why I expected different behaviour.
