452359 - VK_BROWSER_BACK skips past named anchors

Status: RESOLVED DUPLICATE of bug 400568

(Firefox :: Keyboard Navigation, defect)

Description

[hat.bugzilla]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.1) Gecko/2008070208 Firefox/3.0.1 (.NET CLR 3.5.30729)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.1) Gecko/2008070208 Firefox/3.0.1 (.NET CLR 3.5.30729)

When browsing a page with named anchors (e.g. for navigating a large page), keys which emulate the VK_BROWSER_BACK keycode (such as, but not limited to, browser navigation keys on laptops) skip past named anchors.

Reproducible: Always

Steps to Reproduce:
1. Browse to a site of your choice
2. Browse to http://www.w3.org/TR/html401/struct/links.html
3. Click any link in the table of contents
4. Press a keyboard key which sends VK_BROWSER_BACK (Even a small test program which sends this keycode to Firefox causes this bug)

Actual Results:  
You will find yourself on the site from Step 1

Expected Results:  
You should be back at the top of the page from Step 2

If you navigate to 2 named anchors in the same page, it only seems to skip one such anchor, landing you at the top of the site, rather than the first anchor, as would be expected.
