fix(frontend/scroll): no callback for disconnected elements

[saschanaz]

What

el.isConnectedチェックを追加

Why

Fixes #.... 忘れました。覚えている方は教えてください

タイムラインを下にスクロールしてノート画面に移動して再び戻ったら以前のスクロール位置を失う問題を修正

画面転換によってIntersectionObserverが発動し、それがonScrollTopをコール、executeQueue()がコールされる問題です

misskey/packages/frontend/src/components/MkPagination.vue

Line 160 in 9487856

backed = entries[0].isIntersecting;

misskey/packages/frontend/src/components/MkPagination.vue

Line 179 in 9487856

scrollRemove = (props.pagination.reversed ? onScrollBottom : onScrollTop)(contentEl, executeQueue, TOLERANCE);
