Drag and drop acts weird, sometimes not resetting the parent, or even clearing the region value

So one problem with drag and drop is that if you move a field or a field group outside a group above the group, the parent is not reset to none. It seems to happen only if you move it to the top of the table.

To reproduce

  1. Create a tabs group and put it on top of the table
  2. Create a tab group and nest this underneath
  3. Nest a field, say the body, under the tab and save
  4. Now drag the body to the top of the table, in the root. Then hit 'Show row weights'. The parent will still be the first tab

Note: after some tests, a simple single group, say details, is good enough to to reproduce this bug! See the small video underneath to see how to reproduce it.

It looks like that is fixed in 🐛 TableDrag JS :first-of-type issues Needs work .

Other things:

  • Tabs also sometimes act weird.
  • I was able to get to a state as well where no region value was set for a field, becoming empty.

Not sure yet how to reproduce these two consistently, will document more when I can.

So this seems like a core problem. But let's see if we can we fix this ourselves as this makes it very tedious to drag and drop groups in general. If you comment out line 332 of includes/field_ui.inc (the library), you hit the same bugs.
