Attachment Details screen allows changes but has no Update button.

After opening Media Library in grid view, I clicked on an image and went to Attachment Details window. Although the fields are editable, there is no Update/Save button visible. I did edit one field and then clicked my mouse in the empty space outside of the field. The work “Saved.” appeared briefly in the upper right corner of the window and then disappeared.

If people are meant to make changes in this window, perhaps add the standard Update button to make the interface more intuitive.
