+ *
+ * What this hook does is:

+ * - on mouse down inside the popup, set closeOnDocumentClick to false
+ * - on mouse up, set closeOnDocumentClick to true
+ *
+ * Usage:
+ *
+ *    const closeOnDocumentClick = useCloseOnDocumentClick()

+ *      <Popup ... closeOnDocumentClick={closeOnDocumentClick} >
