820031 - jQuery mouseenter/mouseover problem in Firefox 17, but same page works properly when shown in an iFrame in Firefox 17

Status: RESOLVED FIXED

(Core :: Graphics, defect)

Description

[D8N]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:17.0) Gecko/20100101 Firefox/17.0
Build ID: 20121128204232

Steps to reproduce:

A popular jQuery powered plugin that uses jQuery and jQuery easing and detects mouseenter/mouseover events DOES NOT work properly in Firefox 17.0.1, but it DOES work if shown in an iframe in Firefox 17.0.1. Below I include the direct link to the plugin implementation AND the working iframed link.


Actual results:

When moving the mouse to the center of the screen, the screen does not animate or split. Clicking near the middle of the screen does invoke some choppy animation, but the plugin has operated on mouseenter/mouseover in previous versions of Firefox without any issue. See the issue below:

Expected results:

For the link below, click on the PROMO example and see that the exact same page operates as intended when it is served inside of the iframe on Firefox:

Fixed by DLBI I guess.

I don't think we're going to get a fix into FF17 for this bug. FF18 will be out soon anyway.

This doesn't meet ESR landing criteria, not tracking.
