console warning message when using ComboBox

We are seeing this error message when using ComboBox component

An example of our use:

<ComboBox
						className="bx--select-input"
						autoFocus={autoFocus}
						placeholder={placeholder ? placeholder : ''}
						light
						onChange={this.handleChange}
						onBlur={this.handleBlur}
						items={this.visibleOptions || []}
						selectedItem={this.selectedOption || { label:'', value: '' }}
						{...attr}
					/>

@dakahn No, unfortunately. Debugging requires knowledge of how Downshift works internally.
