映像の固有寸法が変わった際に、両方の表示で移動位置を再制約してください。 両コンポーネントは loadedmetadata を処理しますが、その後の固有寸法変更を処理しません。ズーム中に画面共有の縦横比が変わると、移動位置が古い制限範囲に残ります。映像要素は固有寸法の変更時に resize を発火します。(html.spec.whatwg.org)
packages/frontend/src/components/MkCallsVideo.vue#L8-L8:videoのresizeイベントでもconstrainを呼んでください。packages/frontend/src/components/MkCallsScreenWindow.vue#L10-L10: 別ウィンドウのvideoにも同じ処理を追加してください。

ドラッグ以外のクリックでは、映像を選択できるようにしてください。
ズーム中は .pan が映像選択ボタンを覆い、@click.stop がクリックを止めます。そのため、マウスでは倍率を100%に戻すまで映像タイルをフォーカスできません。ドラッグ後のクリックだけを抑止し、通常のクリックでは select を発火させる方法をご検討ください。

倍率の上限・下限では、スクロールを止めないようにしてください。
100%で縮小方向、または400%で拡大方向にホイールを回しても、倍率は変わりません。それでも preventDefault() が親要素のスクロールを止めます。計算後の倍率が現在値と同じ場合は、既定動作を維持してください。

What
通話内の画面共有と別ウィンドウで、スクロールによる100〜400%のズーム、右下の倍率スライダー、拡大中のドラッグ移動に対応します。ポインター位置を中心に拡大し、映像の縦横比に合わせて移動範囲を制限します。100%に戻すと位置もリセットされます。
通常表示(100%)
スクロールで200%に拡大
ドラッグ移動後・別ウィンドウ・スマートフォン幅
Why
画面共有の細かい文字や図を拡大し、見たい範囲へマウスで移動できるようにするためです。
