Hi,

We are Facing a problem after upgrading ExtJS to 6.2.1 from 6.0.2

In 6.0.2 we were able to navigate the YESNO button via left and right arrow keys, but after upgrading to 6.2.1(same issue with 6.5.1) we are unable to navigate via arrow keys.

If you check the third example in the Sencha doc Ext.window.MessageBox
http://docs.sencha.com/extjs/6.0.2/c...essageBox.html
and
http://docs.sencha.com/extjs/6.2.1/c...essageBox.html

The arrow keys are working in the 6.0.2 example and not working in the 6.2.1 example
