We noticed that on our multi-select field, when using the enhanced user interface, an in-line width is applied to the input that is not applied when using the standard display. For example, the standard display can have the width changed by selecting the field size while the enhanced interface cannot.
<input type="text" value="Click to select..." class="default" autocomplete="off" style="width: 115px;" tabindex="2">
We don't really have any control over the width because of this. Is that intentional?
