"Columns to Display" cannot be selected in a Filter Results gadget when a field with a name longer than the width of the multi-select box exists

We have several form fields with long verbose field names along the lines of "If you answered yes to any of the above questions, have you received approval from the head of the department?". These fields worked fine in JIRA 3.13, but if such a field exists in JIRA 4.0 it will be impossible to configure the "Columns to Display" box on the configuration page for the Filter Results gadget. The vertical scroll bar ends up pushed "under" the right edge of the gadget and can no longer be used. I have not found equivalent keyboard shortcuts that would allow you to multi-select non-continuous items in the field, so it would appear that this scroll bar is required in order to set these values.
