Expected / Desired Behavior / Question

On selection change, selectedList should be highlighted and options should not be repeated

Observed Behavior

On ListPicker selection change, selectedList is getting highlighted but the options are binding again

Steps to Reproduce

After migrating my project from SPFx 1.6 to SPFx 1.8.2 I started seeing this issue.
If we don't set the selectionList from state then we wont have issue. But in my scenario I need to set the selectedList from state and it should be stored back to the state on selectionChanged event

Thank you for reporting this issue. We will be triaging your incoming issue as soon as possible.

After some research we think it's related to the control pushing all found lists to the _options, without checking if the item is already in this list. As this function is also called on any change done to the selected item it will duplicate all items again and again on change. It's unclear to us why this issue started after upgrading our project.

A proposed solution would be to check if the item is already in the list before pushing;

results.value.map(list => {
        if (!this.optionsContainsList(list)) {
          this._options.push({
            key: list.Id,
            text: list.Title
          });
        }
      });

This should have been fixed. You can test it out in the latest beta version and will be available in 1.14.0. More information on how you can test out a beta version can be found here: https://sharepoint.github.io/sp-dev-fx-controls-react/beta/
