Vue: Maximum call stack size exceeded in v-bind:class using $slots

[Leopoldthecoder]

Version

2.5.14

Reproduction link

https://jsfiddle.net/mmx38qxw/568/

Steps to reproduce

Run the fiddle

What is expected?

Render without error

What is actually happening?

Console warns that maximum call stack size exceeded

---

This demo works fine in prior versions, so it might be a regression in 2.5.14. Another find is that if I don't pass <span slot="append"> to <compo>, there'll be no error.

It was introduced in https://github.com/vuejs/vue/commit/956756b1be7084daf8b6afb92ac0da7c24cde2a5, as a workround, you can use something like:

{
  template: `
    <div :class="{ 'has-slot': !!$slots.append }">
      <slot name="append"></slot>
    </div>
  `
}
