Steps to reproduce the problem:
1. Allow all popups (Settings > Content Settings > Pop-ups > Select "Allow all sites to show pop-ups")
2. Go to https://www.googledrive.com/host/0B9U4zVhqBiz7ai1Cb25JelBXeDA
3. Click "Open and Focus Window" link.  The first time this link is clicked it opens a new window and focuses on the window.
4. Leave the opened/child window open and return to the parent window.
5. Click "Open and Focus Window" link again.

What is the expected behavior?
Child window should be focused (brought to foreground).

What went wrong?
Child window is not focused (not brought to foreground).

Customers for our site must allow pop-ups.  The window.focus call fails even if the parent window holds on to a reference to the child window after first opening it.
