disabled parents in treeview will not open

[TermeHansen]

When setting a parent to disabled, it will not open or close, seems like an issue here as it works fine in pure vuetify.

import ipyvuetify as v
items = [{
  'id': 1,
  'name': 'Applications :',
  'disabled':False,
  'children': [
    { 'id': 2, 'name': 'Calendar', 'disabled':True },
    { 'id': 3, 'name': 'Chrome' },
    { 'id': 4, 'name': 'Webstorm', 'disabled':True, 'children': [
        { 'id': 5, 'name': 'Test'}]},
  ],
}]

v.Treeview(items=items, selectable=True, item_disabled='disabled', v_model=[2])

It is a bug in the version of Vuetify (v2.2.26) which is used by ipyvuetify.
