click "with autodisable"
ZK-4866, try this case: https://zkfiddle.org/sample/1vi7oet/1-focus-with-autodisable
the button changes it's label -> OK
the label gets focused -> OK
(sometimes - style is flickering for a fraction of a second)
the button receives the focus after a short time "stealing" the focus from the label
the label remains focused
when pressing the second button "no autodisable' or 'no label change'
this happens when the button has both autodisable enabled and a changing label at the same time
when focusing native dom elements directly zk.currentFocus needs to be cleared.
(not necessary when using client side Widget.focus(), or server side focusing)
