Using jQuery 1.7.1, I have noticed that the value attribute/property of a text input field does not update when I view it in Firebug's Inspect Element tool, but does update on the screen, i.e. in the actual visible text box.

For example, when changing the value of a text with the following (used inline):

jQuery(function() {

jQuery('#event').val("test");

});

the text box itself displays test but Firebug's Inspect Element does not represent the change:

<input type="text" value="" placeholder="" id="event" name="event" class="input-text">

I'm sure I have seen the value change in Firebug before using older jQuery, however not in this scenario, nor that of a colleague of mine also using jQuery 1.7.1.

Is this a quirk/bug of this particular version of jQuery or have I missed a step somewhere?
