[9] Review request for 8056915: Focus lost in applet when browser window is minimized and restored

[Alexey Ivanov]

Hello AWT team,

Could you please review the fix:
    bug: https://bugs.openjdk.java.net/browse/JDK-8056915
    webrev: http://cr.openjdk.java.net/~aivanov/8056915/jdk9/webrev.00/
Description:
After user minimizes the browser window and then restores it, the focus 
does not return to the applet.
The fix preserves the latest focus owner in the browser window so that 
applet gains focus when the browser window is restored.

Thanks,
Alexey
