Save data reordered/sorted

Looks good, makes sense and fixes the issue.

@urvashi_vora There is no difference between your MR and the patch in #3, correct?

Yes, committed the changes to help the maintainers and to save their efforts.

Thanks for pointing this out, patching and reviewing.
The sort/save seemed to be working on Claro, but could replicate using the Gin admin theme.
Can confirm patch #3 works and applies ok.

Committing, closing and giving credit.
