after 19.1.1 update moving deselected chip changes the selection of other chips not respecting the [selected] in mat-chip-option

### Reproduction

I have create a minimal reproduction of the issue

https://github.com/Siddhu-K/chip-drag

toggle chips and drag drop.

```

@for (i of chip_list(); track i; let index = $index) {

{{ index + 1 + ". " + i.name + " - " + i.selected }}

}

github.com/Siddhu-K/chip-drag にあるリンク先の最小再現から始め、チップを切り替えてから選択解除されたチップをドラッグして、問題を再現します。mat-chip-listbox、mat-chip-option [selected]、および cdkDropList の間の相互作用を追跡します。並べ替え後も、表示される選択状態が各チップの selected 値と一致していれば完了です。
