Trigger 'click' with leveled slots causes "Duplicate presence of slot"

[nerdcave]

Version

1.0.0-beta.12

Reproduction link

https://gist.github.com/nerdcave/a76cbed0bb92bb93972f0232d9c8a1c0

Steps to reproduce

Run the test with Jasmine.

What is expected?

No warnings.

What is actually happening?

ERROR: '[Vue warn]: Duplicate presence of slot "content" found in the same render tree - this will likely cause render errors.

---

• The warning will go away if you 1) remove the wrapper.find('div').trigger('click') -or- 2) remove slot-scope="props" off the template.
• I don't have these issues in 1.0.0-beta.10.

Thanks for the bug report and the test case.

This issue has been fixed in beta.13.

I've added a test case to avoid future regressions
