Describe the Bug

I have a long list of elements, and I want to group them. The list is grouped correctly, but collapse and expand the group is not working correctly, seems that the items doesn't collapse and they duplicates themself. I hope the video helps.

This can be reproduced on the rsuite documentation just adding more elements to the Group example.

Expected Behavior

When collapse, the actual group collapses and hides the elements. When expanded, the elements are visible but there are only the same elements, no duplicates.

To Reproduce

import { InputPicker } from 'rsuite';

const data = ['Eugenia', 'Bryan', 'Linda', 'Nancy', 'Lloyd','Eugenia', 'Bryan', 'Linda', 'Nancy', 'Lloyd','Eugenia', 'Bryan', 'Linda', 'Nancy', 'Lloyd','Eugenia', 'Bryan', 'Linda', 'Nancy', 'Lloyd'].map( item => ({ label: item, value: item, role: Math.random() > 0.5 ? 'Owner' : 'Guest' }) );

const App = () => ( <> <InputPicker creatable data={data} w={224} groupBy="role" placeholder="Group Select" onCreate={(value, item) => { console.log(value, item); }} /> </> );

ReactDOM.render(, document.getElementById('root'));
