Have a one2many in a form view. It displays its records with a kanban. Add a record, now click on that new record. Before this commit, there was not "Remove" button, preventing to effectively remove a new (virtual at this point) record from the one2many. Aftet this commit, there is a remove button that effectively removes the record from the one2many. closes odoo/odoo#97775 Signed-off-by: FrancoisGe <fge@odoo.com>
