I would've expected this CL to remove those conditional checks and always call
PrepareForCommit without caring about BeforeUnload acks at all. As discussed
over chat, let's look into how to improve those in a separate CL, as this code
seems suboptimal.

[carlosk, 2015/03/04 09:46:55]

Acknowledged. The fix for that would add a lot more changes to this CL possibly
going over non-content files. A new PlzNavigate issue was created to track this:
