Sorting hasMany relationships

[lethal flicker]

The documentation mentions that hasMany relationship fields can be made sortable using the isSortable admin option:
https://payloadcms.com/docs/fields/relationship#admin-options

This doesn't seem to have any effect for me, am I doing something wrong?

{
   type: 'relationship',
   label: 'Boxes',
   name: 'items',
   relationTo: 'iconBoxes',
   required: true,
   hasMany: true,
   admin: {
      isSortable: true
    }
}

The items cannot be dragged or sorted in any other way that I can figure out (see attached screenshot).

What payload version are you currently using?

Currently on 3.78.0

Weird. I have a relationship field without

admin: {
isSortable: true,
},

And i can still sort my relationship field. Could you try removing admin: {} and see if its sortable then?

Nope, still not working. I'm using some other hasMany relationship fields in other collections and none of them are allowing me to sort it seems. Tried a different browser too just in case. When I hover over one, the cursor changes to a "grabbing" hand icon but trying to click and drag and nothing happens.

But, if it works for you then my guess is this is being caused by something in my payload setup. I will try some things and come back later

Whatever is causing it, it seems to be something introduced in 3.78.0. If I rollback to 3.77.0 drag and drop reordering of relations works perfectly. Upgrading back to 3.78.0 makes it stop working again.
