277231 - writing content generated by javascript into iframe ads pages to history and breaks back button

Status: RESOLVED INVALID

(Core :: DOM: Navigation, defect)

Description

[info]

User-Agent:       Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; de-DE; rv:1.7.5) Gecko/20041122 Firefox/1.0

i have a javascript function HighlightSearchTerms() which writes content into 
document.body:

bodyText = HighlightSearchTerms(bodyText);
document.body.innerHTML = bodyText;

When calling the script, it also writes content into the iframes on that page.
This adds pages to the browser history (number of iframes = number of 
additional entries in history) and renders the back button of the browser 
useless. Same happens when calling a form in an iframe. this does serious 
trouble. example: remote scripting with location.replace()

Reproducible: Always

Steps to Reproduce:
1. go to http://www.dancefloorstars.de
2. use the search box
3. look at the browser history and try to use the back button

Actual Results:  
browser back button not working
javascript:history.go(-1) etc. not working

Expected Results:  
do not add identical pages to browser history. When calling iframes, no 
additional pages should be written into history.

Added: Script deactivated because of Mozillas different "innerHTML" 
interpretation. So, bug not reproducable at this time (high traffic website).

If it's not reproducible, we can't do anything about it.  Marking invalid, since
there is no way to reproduce the bug.  Please reopen when there is a page or
testcase attached to the bug that can be used to reproduce

Note that a bug with a very similar description has been fixed since Firefox
1.0, so you may want to retest with a current trunk build.  I'll bet even money
that this is fixed.
