Combobox findDOMNode is deprecated in StrictMode

[dlferro]

I've run into this warning using the combobox with React 17. It appears that it was tackled previously with popovers. @interactivellama is the gist of this issue just replacing it with components reference? I'm assuming in this instance it's a utility or sub component of comobox.

This is likely an issue found in the https://github.com/salesforce/design-system-react/blob/master/utilities/keyboard-navigate.js and https://github.com/salesforce/design-system-react/blob/master/utilities/keyboard-navigable-dialog.js which calls findDOMNode to check for event target.

yes, it likely can be updated to compare refs.
