1552419 - preventDefault does not work on keydown when "space bar" is pressed

Status: RESOLVED DUPLICATE of bug 1487102

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

Description

[milko.venkov]

Attachment: buttonClick.html

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/73.0.3683.103 Safari/537.36 OPR/60.0.3255.84

Steps to reproduce:

I have a button and I handled keydown event. In the handler I am calling preventDefault. When the button has focus and I press space bar it also fires click event which is not correct. If the button has focus and I press Enter key click event does not fire.
Click event does not fire in MS IE, MS Edge, Google Chrome and Opera.

Actual results:

Click event fired on space bar press event preventDefault is called

Expected results:

Click event should not fire.

The bug doesn't seem to be resolved, though marked as duplicate, it exists in Firefox 72. On trying to handle keydown event, it still executes keydown and then click event.

You can clearly see it's a duplicate of a report that's still open.
