ui sortable between tabs and height

Question

Hi,

i am having sortable list between tabs (jquery ui) that works fine

My problem is that when the list move to other tab it adds the width and height

Original Item :

<li>Item 1</li>

Item after move to other tab

<li style="display: list-item; height: 17px; width: 120px;">Item 1</li>

Is there any way to prevent this.
