Vuejs.org: The example given for "Disabling Attribute Inheritance" doesn't work

[estyh]

The docs show an example for how to disable attribute inheritance (https://vuejs.org/v2/guide/components-props.html#Disabling-Attribute-Inheritance) - I tried, and it doesn't work!
In this example, the placeholder is passed to the input, but class is not, it is applied to the root-element, label. Are the docs wrong, or is something broken in Vue?
As a side note, the example uses a label prop for the child component, but doesn't pass it in as an attribute.
Here is my js-fiddle example, almost straight out of the docs (with some css for clarity)

From docs:

Note: this option does not affect class and style bindings.

Perhaps this note could appear in guide, too?

[LinusBorg]

Indeed. And the example should not use class, of course.

Would you be interested in doing a small PR?

@LinusBorg I'll give it a try.

@leopiccionia Any progress on this one?

@phanan I've closed my original PR, I'll open an improved one yet today.
