component.focus() doesn't work since version 7.4.4

I had an app wich showed a modal window and focused to a component. This has been working in 7.4.1, … I’m not sure, but from 7.4.5 or 7.4.6 focus doesn’t work. I’ve tested to focus first the window and then the component, but nothing at all. Any ideas? Maybe a bug?


Just tried a very simple case (a single textfield to be focused within a window) and that seemed to work just fine. Can you provide some code that reproduces the issue?
