Drag and drop upload issue in repeater

Drag and drop upload does only work on the first image field in a repeater, only when you save the entire entry, add a new row to your repeater you can drag and drop upload another image. But you can't drag and drop upload multiple image in multiple repeater rows without saving.

• To replicate, create a repeater field with images.
• Create a new row in the repeater, and drag and drop straight intro the first repeater row, this works.
• Add a new row in the repeater, and drag and drop straight intro the second repeater row, this fails.
