BUG: Descendent Selector Broken in 3.4.4

[bdwain]

Describe the bug
The descendent selector (.find('.foo .bar')) seems to have broken in the latest release. It seems to have been broken in #1680 .

I have a component that returns something like

//note: Button is a component
<div className="button-group">
  <Button classname=".foo" onClick={this.handleFoo}>foo</Button>
  <Button classname=".bar" onClick={this.handleBar}>bar</Button>
</div>

and then this fails because find returned 0 nodes

const wrapper = shallow(<ButtonGroup />);
wrapper.find('.button-group .bar').simulate('click');

To Reproduce
Working on a reproduction. Will add it when it's ready. See example above though.

Expected behavior
The call to .find should return a wrapper around the second button

Desktop (please complete the following information):

• OS: OS X High Sierra
• Browser Chrome
• Version: 68

Additional context
The error began when upgrading from 3.4.1 to 3.4.4. I was able to remove it by reverting only the one-line change in #1680 in my node modules directory.

Versions:
Enzyme: 3.4.4
enzyme-adapter-react-16: 1.2.0
enzyme-adapter-utils: 1.5.0
react: 16.4.2
