<transition> is breaking/flickering when toggling really fast (spam clicking a button to toggle) #2482
Description
Version
3.0.2
Reproduction link
https://codesandbox.io/s/nervous-hooks-blcjw?file=/src/App.vue
Steps to reproduce
Spam click the Show Overlay button
What is expected?
The fade transition should smoothly toggle between opacity: 0 and opacity: 1. no matter how fast you click.
What is actually happening?
The fade transition constantly shows/hides abruptly while spam clicking.
Exactly same transition works smoothly in Vue 2 here I am attaching sandbox for that.
