Dcc Dropdown in 1.0.0rc1 throws error in IE11

In IE11, with dash-core-components 1.0.0rc1 the dcc Dropdown throws JS error

Objects are not valid as a React child (found: object with keys {$$typeof, type, key, ref, props, _owner}).

When clicked in the browser.

No error in Chrome or Edge

With dash-core-components 0.25.0 it works OK in IE11

I wouldn’t recommend using the 1.0.0rc1 versions in production, they are really just proof-of-concepts.

OK, thanks. I’ll stick with 0.25.0
