Steps to Reproduce

compare the 2 chosenboxes:

<chosenbox width="200px"/>
<chosenbox width="50%"/>

start typing longer words into the input fields, which don't fit any more

Current Result

when using a pixel width the text field grows to cover the whole chosen box
for percentage the input field grows up to 40 pixels (50-10)

Expected Result

correctly calculated input field size based on the actual widget width
e.g. element.clientWidth or element.getBoundingClientRect()

Debug Information

the percentage value is parsed as an integer so 50% becomes 50px - 10px paddings
