Trigger = "click" breaks mouse interaction with components in it.

In the example below, I have Popover that contains Select (from react-select). If Popover trigger is set to "click", then trying to select elements in the drop-down list as well as using its drop-down button closes the popover instead of allowing the interaction.

Using keyboard or trigger="hover" are two workarounds that I found that allow to select elements in a drop-down by clicking.

react-selectを含む、クリックでトリガーされるPopoverを使って、リンク先のCodeSandboxのインタラクションを再現してください。まず、このrepositoryでclick-triggerの処理を追跡し、dropdown内のクリックによってPopoverが閉じる理由を特定してください。dropdownの選択とそのボタンが、予期せずPopoverを閉じることなく機能すれば完了です。
