Window.focus doesn't work if the context root is different from the parent and child

Hi

I have a use case where i need to open a url in the new window and show that in front but currently it's not happening in the below scenario.

If i open the window(Url abc.com/xyz) from a page whose context root is abc.com then the window opened will go back(Context Url's are same).

If i open the window(Url def.com/xyz) from a page whose context root is abc.com then the window opens in the front and it's our expectation always(Context Url's are different).

Much appreciate your help.

Thanks,

Naga
