iOS: Toolbar on TextField doesn't hide smoothly when calling blur

Setup:

>Textfield with a Ti.UI.IOS.Toolbar with one button.
>Click eventlistener on the button which calls .blur() on the textfield

The keypad slides down, leaving the Toolbar at the top. When the keypad has slid off the page, only then does the Toolbar start to slide down.

Sample code:

Causes a noticeable flash for the user.

<TextField id="txt_contactNumber" class="txt_inputshort">
<KeyboardToolbar>
<Toolbar id="numberToolbar" bottom="0">
<Items>
<Button id="flexSpace" systemButton="Ti.UI.iPhone.SystemButton.FLEXIBLE_SPACE" />
<Button id="cancelContact" systemButton="Ti.UI.iPhone.SystemButton.DONE" />
</Items>
</Toolbar>
</KeyboardToolbar>
</TextField>

$.cancelContact.addEventListener('click', function()

);
