When the component is bundled with 'v-model', if the 'v-on = "$ listeners"' attribute is added, the 'input event' will be passed up. 'Value' is eventually '[object Event]'

What is expected?

input的值为输入的值

The value of input should be the value entered

What is actually happening?

input标签将'input event'传递给父组件
导致value为[object Event]

The input tag passes 'input event' to the parent component
Causing value to be [object Event]

---

此情况在2.5.0之前.虽然依然会将event通过input传递给父组件.但并不影响最终结果.
在2.5.2则将会影响最终结果

This is before 2.5.0. Although the event is still passed to the parent component via input, it does not affect the final result.
At 2.5.2 will affect the final result

This is a wontfix, because the emitted events need to be in correct order (as fixed in #6805). It only happened to work previously because the native event was emitted first and then overwritten by the custom event.

You can preserve the old behavior by emitting the custom event in a nextTick, so that it overwrites the native event: https://jsfiddle.net/50wL7mdz/72174/
