If there is more than one page of variations in the variations frame, and you trash everything on the last page, you get stuck on an empty page with no way to get back #1943
Description
Assume there are 20 variations displayed per page in the variations frame on the Edit Product page. If I have 24 variations, and I trash 21-24 from the 2nd page of variations, I get shown an empty page in the frame, with no link back to the first, (or previous), page of variations.
The only way back to the first page of variations is to refresh the whole web page.
