Misreported data type in inspector

[9mm]

Version

6.0.0-beta.8

Browser and OS info

Latest Vue@next / Latest OSX / Latest Chrome

Steps to reproduce

Create a prop with this signature:

disableStart: {
  type: [Date, Boolean],
  default: false,
},

Now inspect the component with that prop in vue dev tools, and look in the right hand pane. Hover over the prop and look at the tooltip summary.

What is expected?

It should display "Date, Boolean" or at the very least "Multiple"

What is actually happening?

It shows "Any" (which is very different meaning than "Multiple")
