29756 - [SPORADIC] Clicking on link while page is still loading leads to incorrect navigation.

Status: VERIFIED WORKSFORME

(Core :: DOM: UI Events & Focus Handling, defect, P3)

Description

[Jason Eager]

Setup:

Load a page with a lot of links or a lot of graphics, one that takes
a decent amount of time to load. Click on one of the links on the
newly loading page when it starts to render.

Expected result: Loading of the old page should stop as smoothly
as possible and navigation should proceed to the page the link
points to.

The expected result only occurs 30-40% of the time. Other times, one of
these three bugs occur:

Unexpected result #1: Browser appears to be navigating to page
indicated by link, but instead continues to load old page. All navigation
stops once the old page is loaded.

Unexpected result #2: Browser appears to get stuck in an endless loop or
an idle loop while throbber and bottom indicator continues to show navigation.
When this happens, hitting the stop button and then reclicking the link
usually leads to the correct page being loaded within 3-4 seconds.

Unexpected result #3: Browser actually reloads the page from scratch that
it was loading when the link was clicked.

I think all of these bugs are related, which is why I put them here..but
I can break them out into separate reports upon request. I'm sure it has
something to do with the event queue.

This is getting really annoying to an impatient browser user such as myself.
I'm almost tempted to mark it as Dogfood, but I don't want to become
known as "The Bug Reporter who cried Dogfood".

jce2, please provide a more concrete test case.  Thanks!

It is unclear whether this bug is event related.  It could also be 
docshell/webshell or session history related.

Setting the target milestone to "Future".

I'm still seeing this every once in a while. I need a qa person to bash on this
for a little bit to see if this has been fixed or not.

I stopped seeing this most of the time since mid may.
