this will break headless mode where window_ is always NULL

[mstensho (USE GERRIT), 2013/05/14 09:28:24]

So would the right thing be to keep the old code for headless?

I.e. "else if (web_contents_) blahblah..." ?

[jochen (gone - plz use gerrit), 2013/05/14 09:31:39]

Not sure. We always want the native view to be the specified size. So if window_
!= NULL, you need to add the size for the url bar etc..

[mstensho (USE GERRIT), 2013/05/14 09:40:16]

I'm sorry, I don't understand. Can you provide me with a test case for
non-headless mode where my change causes problems?
