Bug 17335 – Calling event.preventDefault() in contextmenu handler disables other mouse event handlers.

• Component: DOM
• Status: RESOLVED FIXED

[Khoo Yit Phang]

If I have a contextmenu event handler and call preventDefault() to disable the standard context menu:

document.addEventListener("contextmenu", function(evt) {
    evt.preventDefault();
    println("contextmenu");
}, true);

all other mouse event handlers seem to be incorrectly disabled (or at least, no events are fired), until the next click.

This misbehavior occurs in the nightlies (tested 30070+).

It works correctly (events keep firing) in Safari 3, as well as Camino and Firefox.

This is occurs under Safari 3.1.

Also, I found that if the oncontextmenu event happens in an IFRAME, the problem does not occur.
