bind() and trigger() fail on plain javascript objects if a method “handle” exists

[rs@…]

This is a regression from the changes made in 1.4.3. The following works fine:

var a = {};
jQuery(a).bind("myEvent", function() {
    jQuery('body').text("Gaga");
});
jQuery(a).trigger('myEvent');

Whereas this does not work:

var a = {};
a.handle = function(){};
jQuery(a).bind("myEvent", function() {
    jQuery('body').text("Gaga");
});
jQuery(a).trigger('myEvent');

Both variants work fine in jQuery 1.4.2. Test case is at ​http://www.jsfiddle.net/ZtKLD/

Could this possibly be related to #7500 ?

Replying to rwaldron:

I don't think so. This probably comes from the changes in 1.4.3 to the data() method, as we now are storing the data() data on plain js objects directly.

Now the events add() method seem to get confused ​here and ​here as elemData.handle is now set when there is a "handle" property on the js object. Which of course it wasn't in 1.4.2 where data() returned nothing on a plain js object unless there was already data associated with it in the internal cache. But in 1.4.2 a similar bug existed the other way around

So the main issue is we really shouldn't be storing a property named handle directly on a js object.
