451738 - "Subscribe to..." menu lists feeds even after link elements are removed from DOM

Status: VERIFIED DUPLICATE of bug 380639

(Firefox Graveyard :: RSS Discovery and Preview, defect)

Description

[Jordan Liggitt]

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

When a link element for an ATOM or RSS feed is added to the DOM via scripting, Firefox notices and adds the new feed to the "Subscribe to..." menu for the page.

When a link element is removed from the DOM via scripting, the "Subscribe to..." menu retains the menu item for the feed until the page is reloaded.

An AJAXy web application that removes and rebuilds content in-page (including link elements to feeds) could amass dozens of feed items with no way to remove them.

Reproducible: Always

Steps to Reproduce:
1. Trigger javascript which creates a LINK element in the DOM for an ATOM or RSS feed
2. Notice the new item in the "Subscribe to..." menu
3. Trigger javascript which removes the previously created LINK element

Actual Results:  
The item still exists in the "Subscribe to..." menu

Expected Results:  
The item would be removed from the "Subscribe to..." menu
