743460 - Stop Button Does Not Terminate Web Page Rendering

Status: RESOLVED WORKSFORME

(Core :: DOM: UI Events & Focus Handling, defect)

Description

[David E. Ross]

Mozilla/5.0 (Windows NT 5.1; rv:11.0) Gecko/20120312 SeaMonkey/2.8

After all desired text from the cited URI has been rendered, SeaMonkey continues to request and receive Internet packets from various Yahoo-owned domains.  Selecting the Stop button on the SeaMonkey tool bar (which is indeed enabled) does not terminate this activity, which is readily observed in the SeaMonkey status bar at the bottom of the window.

Chances are, the patch has an interval timer which is doing requests.  The stop button does not stop scripts.  Hard to say without a smaller testcase.

Scripts:  I have seen this problem with JavaScript disabled.  

Test case:  I can remember seeing this problem only at the cited URI.  Furthermore, it does not always happen since the page changes frequently.  I would not know how to contrive a smaller test case because I don't know what is causing the problem.  

The next few times that I see this problem at Yahoo news, I will try to remember to capture all the HTTP headers via the LiveHTTPHeaders extension.

In the case of comment #3, receipt of Internet packets stopped.  However, the Stop button remain enabled, the SeaMonkey icon continued to show bubbles rising, and the status bar remained with 
     Transferring data from l.yimg.com...

I have also seen situations at Yahoo News where the receipt of packets continued and the status bar kept changing.

Do you have a reduced testcase?

I stopped visiting the cited Yahoo URI because of editorial problems with that site.  (The site continued to report "recent news" 1-3 months after the event.)  I just now tried to recreate the problem by visiting the cited URI and could not.
