Goto http://java.sun.com/j2se/1.5.0/docs/api/index.html. Note the title is "Overview...". Now click some class names in the lower left pane. Press and hold the back button. The oldest item that should still be "Overview..." is now titled the same as the last class page that was loaded. At the HTML level, what's happening is that whenever a frame loads it sets the parent.document.title to be specific to that newly loaded frame. The same is also true for the history item for the overview page - its title also changes as the page changes its title dynamically. I don't think this is very desirable behavior from the user perspective, but given the page keeps changing it's title, it's not as clear to me that this is technically incorrect.
I checked WinIE, and they do not allow the title of the history item to change due to subsequent loads, **while the window is open **. When you open a new window and look at history, then the item has the newly requested title. So perhaps they let the items title change, but just don't have any way to track that change dynamically in their history UI.
Created attachment 2912 [details] patch for bug 3953
Comment on attachment 2912 [details] patch for bug 3953 Looks very good to me (bug fix plus code simplfication, yay!). Whoever commits this should verify that it fixes the specific bug reported here (the oldest title in the Back button's menu should be Overview after the fix).
Landed this patch, and verified fix.
