[amaieras]

Environment

Vuetify Version: 3.7.3
Vue Version: 3.4.27
Browsers: Chrome 130.0.0.0
OS: Mac OS 10.15.7

Steps to reproduce

Click on the Cost column until you sort asc and expand Pools row

Expected Behavior

Since sort-by prop was not passed, the order of the displayed data should be given by the order in the items array

Actual Behavior

Doing a custom sort inside the filteredItems, parent - children sorting (parent first then its children sorted then another parent and so on) because internal sorting of the v-data-table is applied the order dispalyed in the table is different than the one returned by the filteredItems even though sort-by prop was not passed to v-data-table
