#next branch no response when insert a v-touch into a slot

[fengma1992]

In the next branch v-touch is used as a component, it's OK to use v-touch in general condition, but When inserting v-touch component into a slot, the touch action doesn't work.
My code is like this:
a.vue:
<my-component> <v-touch tag="button" @tap="click">confirm</v-touch> </my-component>

myComponent.vue:
<template> <div> <slot></slot> </div> </template>

When I clicked the confirm buttom, nothing happend and there is no event captured in Vue devtool.
