That would only be a bug if it happened to Ext.dom.Query, not Ext.ComponentQuery. Ext JS components do not necessarily have to be represented in the DOM, they can be sitting in the memory waiting for the right moment to be rendered.

Try this:
Ext.create('Ext.Component', {
name: 'cool'

The above is correct, components don't need to be rendered to be queryable.
