MaterialAutoComplete.setFocus(true) does nothing
It appears that the call to **uiObject.getElement().focus()** in **FocusableMixin.java** results in **focus()** getting called on the underlying **DIV**, rather than on the **INPUT**, which is nested 3 levels deeper.
The issue is related to **AutocompleteType.CHIP**
