Other comments

The label slot seems so be renamed to the title slot. The documentation needs to be adjusted. https://vuetifyjs.com/en/components/treeview/#append-and-label

Documentation is wrong, but also prepend slot doesn't return open so folder icon doesn't change to "open folder" when expanding.

It seems the slots are only used for leaf items, and there does not seem to be slots for groups. As you can see here only empty folders behave correctly

  <v-treeview
    ref="treeview"
    class="treeview"
    active-class="treeview-active"

    return-object
    activatable
    hoverable

    :items="nodes"
    item-children="nodes"
    item-value="path"
    item-title="label"

    density="compact"
    :selected="selected"

    @update:activated="select"
  >
    <template v-slot:prepend="{ item }">
      <v-icon>
        {{ item.open ? 'mdi-folder-open' : 'mdi-folder' }}
      </v-icon>
    </template>

    <template v-slot:item="{ item }">
      <div>
        {{ item.value }}
      </div>
    </template>

    <template v-slot:append="{ item }">
      <div class="append_bold">
        {{ item.count || 0 }}
      </div>
    </template>

  </v-treeview>
