1542725 - JQuery | .click function not working on icon class in latest ESR release

Status: RESOLVED FIXED

(Core :: DOM: Core & HTML, defect, P4)

Description

[santjosie]

Attachment: jquery.html

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:66.0) Gecko/20100101 Firefox/66.0

Steps to reproduce:

I have created an HTML file with a button. The button contains an icon. There is a JavaScript file which has code to print a message to the browser developer console when the icon is clicked.

Attaching the html file used.

Actual results:

Everything works fine in Chrome and latest Firefox version (66.0.2 (64-bit)) but does not work in latest Firefox ESR version (60.6.1 esr).

I have uploaded a video showing the difference in behaviour between Chrome and Firefox ESR (please note, I did click inside the icon image itself and tried).

I then installed the latest version of Firefox (non-ESR) and it works fine.

Expected results:

On clicking the icon, the log message should have been printed.

Hi,

I followed the steps and I have managed to reproduce this issue on latest Firefox ESR version (60.6.1 esr).
I also tested on FF release (66.0.3), latest Nightly (68.0a1) and Beta version (67.0b9) using OS-es Windows 10 and Ubuntu 18.04 and in this versions the issue is not reproducible, the log message is printed.

I will add a component in order to involve the development team in reviewing this issue. If this is not the proper component, please feel free to change it to a more appropriate one.

Thank you for your report.

Thank you for reporting.

AFAICT, the event listener gets added.

ESR60 is near the end of its lifecycle, so this is most realistically going to be taken care of by 68 becoming ESR. I'm timing out trying to figure out what's wrong here, but given an analysis of what goes wrong, we could still try to fix this.

Verified it works with ESR 115.
