I'm facing some severe memory leak issues recently. After some digging, I found that RecycleScroller haven't been destroyed under certain circumastances.
vue-resize/src/components/ResizeObserver.vue
Line 39 in 2f6c090
the code above can't actually remove the event listener, instead, we should assign the value to
null:And the reference to
_resizeObjectshould also be removed, to allow GC of the entrie DOM tree, see: https://developers.google.com/web/tools/chrome-devtools/memory-problems/heap-snapshots#uncover_dom_leaks
