Hi, though in edit page of user profile I have field for the page title, it doesn't override the default page title - stays username and site name...
In 6.x-2.3 it works fine - I had to get back to old version. Also noticed that in 6.x-2.5 style of the table is strange - left column is adjusted to right side.
I had the same problem. Take a look on my patch.
Also applies to new password page, etc
