Hi Alexey,

Thank you for the review. Unfortunately it is impossible to create the automated standalone test for this issue.

In particular if requestFocus() is invoked for some component located at inactive frame it is necessary to activate the frame via CPlatformEmbeddedFrame.requestWindowFocus() to make such focus transition possible.

However that method does nothing, (i.e. no activation happens). As a result the focus cannot be transferred to the component because its owner is not active.
