Current behavior
setting clearOnBlur does not remove input text for every scenario. See reproduction steps for details.

Expected behavior
setting clearOnBlur to true should remove tag-input text everytime the control is blurred.

Minimal reproduction of the problem with instructions (if applicable)

• set clearOnBlur to true
• type something in tag input
• blur input immediately / do not wait for dropdown to show autocomplete items -> input text is removed as expected -> OK
• type something in tag input again
• wait for dropdown to apear with some autocomplete items
• blur the input without setting focus on autocomplete items -> input text ist removed as expected -> OK
• type something in tag input again
• wait for dropdown to apear with some autocomplete items
• hover over one of the autocomplete items / put focus on it with keyboard (by pressing keydown)
• do not select any item, just blur the control by mouse-left-clicking somewhere outside the control
• item is not selected / dropdown is closed / input text remains in input but should be deleted - NOT OK
