I changed the label for title to something with 5 words long, such as "title of your post."
When I go back to the manage fields page, 2 of my fields no longer have the drag and drop handles for reordering.
When I changed the label back to "title", the crosshairs came back.
As a workaround, it is possible to do temporarily change the title label back, reorder, and then change title label to the long one.
However, it'd be great if this can be fixed in the next release as I'm afraid of the workaround failing. Thank you.
