imageWidth not working in form type: mediafinder

Hi.
The preview image is loaded as is without resizing

fields:
    img:
        label: 'konvertagency.landing::lang.txtimg.img'
        mode: image
        imageWidth: '200'
        imageHeight: '100'
        span: auto
        type: mediafinder

Looks like you found a bug! It should be fixed in the next patch. Thanks
