[jdgrimes]

When editing an image on the attachment's Edit Media screen, there needs to be more padding at the bottom of the Image Crop and Thumbnail Settings boxes.

See attached screenshot.

The problem seems to have been introduced in 3.9. See image_edit_38.png​ and image_edit_39.png​ for comparison.

Fixing paddings & margins on edit media meta boxes.

Just added a patch that takes care of these.
Looks fine in both media edit page and media edit in modal.
This solution will work for custom / future meta boxes as well, as the spacing comes from the boxes themselves, and not from their internal content.
