Clicking searchwidget while refreshing collapses other actionbar items

[EsbenGaarsmand]

If a user clicks refresh and then the searchwidget while refreshing all actionbar items except from searchwidget will collapse. This can be confirmed in the Styled Sample by doing following:

1. Click refresh.
2. While refresh is spinning click quickly on the searchwidget.
3. Close the searchwidget by clicking the cross in the right side.
4. Now the searchwidget will be the only visible actionbaritem (except from title and home).

Please create a pull request on the dev branch which adds an example to the 'known-bugs' sample demonstrating the behavior.
