Steps to reproduce

The premise is that you have an iPhone with the system version IOS9.
The Steps to reproduce seem to be a nested amount of custom components.

The problem happened in 2.6.x. I had discovered this problem a year ago. Since I couldn't provide a minimal reproduction at the time (and it is now), I have been rolling back to 2.5.x until now.

But I now find the source of the problem in the source code.
https://github.com/vuejs/vue/blob/v2.6.11/src/platforms/web/runtime/modules/events.js#L69.

In IOS9, Condition "e.timeStamp >= attachedTimestamp" is never holds.

console.log(e.timeStamp, attachedTimestamp); // In IOS9, eg: 1585822331076 1585824221635

You can compare 2.5.x to solve this problem.

What is expected?

touch event trigger

What is actually happening?

events of the touch series are not triggered

---

Only happened in 2.6.x, only events of the touch series
