Request for review 7150345: [macosx] Can't type into applets

[Dmitry Cherepanov]

Hello,

Here's a fix for a regression introduced by recent focus changes [1] 
(7129825). With the fix for 7129825 applied, we started rejecting 
cross-application focus requests and the proposed change partially 
reverts the focus changes to fix the embedded frame bug.

Thanks,
Dmitry
