145841 - Changing an IFrame's position style causes back button to stop working

Status: RESOLVED DUPLICATE of bug 52334

(Core :: DOM: Navigation, defect)

Description

If you change the position style of an IFrame (eg using javascript) and then use
try to use the back button, the back button does not work. See the test case
(http://www.solutionsfirst.com.au/~brian/iframe-test/page1.html) for an example.


Reproducible: Always
Steps to Reproduce:
1. Go to http://www.solutionsfirst.com.au/~brian/iframe-test/page1.html
2. Follow the link at the bottom of the page
3. Click the little arrow button
4. Use the back button


Actual Results:  Nothing happens. To go back you must use the back button's drop
down history.

The test case contains several methods for achieving this result (a button, and
three sorts of text links). If you use the test link which has its href set to
'#' then if you click the back button three times it will return to the start page.


Expected Results:  When you click the back button it should return to the start
page (ie page1.html).

This expected behaviour can be observed under MSIE6.0.


It appears that similar behaviour occurs when writing to an iframe according to
Bug 129590.


This behaviour is not new. I have been experiencing it for several months.


Another example can be observed by:
1. Go to http://www.solutionsfirst.com.au/~brian/nsforum/search.php
2. Click 'search'
3. Click any of the little calendar icons
4. Try clicking back

This is fixed now that reframing an iframe does not recreate the docshell for it...
