When the location.hash is changed in a document loaded in an Iframe, history entries are not always created correctly. This has been tested in OS X Safari Version 4.0.4 (5531.21.10) / Windows Chrome 18.104.22.168 / OS X Webkit nightly r51669
Given an Iframe like this: <iframe src="page.html#begin"></iframe>
If that page.html location.hash is then set to #middle and #end, when the back button is pressed, #middle can be reached, but #begin cannot.
This page has a complete description and working example:
This may be related to bugs 14959 and 17333, but I felt this description was sufficiently different to warrant a separate ticket.
I have also come across this. Other major browsers like Firefox and IE 6/7/8 all work correctly.
I also came across this.
Why this is not getting any attention ?
I am not able to reproduce this in current WebKit nighly builds (r66819) or the current Chrome stable channel (version 6.0.472.53, cut around WebKit revision r63707).
Since I'm pretty sure that http://trac.webkit.org/changeset/61207 is what fixed this, I'm marking this as a dupe of the bug that was attached to.
