animation on input or textarea results in loss of cursor and possibly keyboard input.

Tested with Wekbit nightly build and FF 3.05

Using code such as the below, animating an input or text area will cause the cursor to disappear for the focused input. On Safari text input is no longer accepted, unless the users clicks back into the input. On FF the

$(".resize").
        focus(function(){$(this).animate({height:"6em"}, 500)}).
        blur(function(){$(this).animate({height:"1em"}, 500)})

There is a demonstration at: ​http://smokinggun.com/temp/webkit_focus.html

The demonstration includes a non-jQuery animation routine which creates the desired results.

Great test case! It looks like the problem is in jQuery.fx.step(). When the animation is complete it sets the css overflow and display properties back to their original values. If both of those are commented out, the cursor stays in the textarea.

Testing the OP's original reduced test case in FF4, FF3.x and Chrome (latest) I see that this issue is no longer prevalent. Closing as worksforme.
