I guess you should be updating leadIndex here as well.

It seems set selectedIndex also changes lead and anchor indexes if index is
nonegative. And here the index should not be negative. So I didn't add it.

Right, must be a recent change to ListSelectionModel.

+      this.inProgramSelection_ = false;
+    },

     /** @inheritDoc */
     get selectedItem() {
       var index = this.selectionModel.selectedIndex;
