Expand searchbar in filter

I have an edit page and have a field mediaowner netbox. As it has 6k items it cant be loaded as dropdown, So i used entity picker and then in the dialog the list opens, But when filter is added it svery small, We cant type anything. Any way to expand this filter.

Attaching the screens for reference
media owner nb edit

Hi,

By default Filter locates nested property filters in three columns with equal width. If the screen width is not enough, set Filter columnsCount="2" or even columnsCount="1".

 <entityPicker id="mediaOwnerNetboxField" property="mediaOwnerNetbox"
                                              caption="Media Owner" dataContainer="stdRowPlanDc"
                                              height="35px" width="100%">
                                    <actions>
                                        <action id="entityLookup" type="entity_lookup" />
                                        <action id="entityClear" type="entity_clear"/>
                                    </actions>
                                </entityPicker>

Here we open the browse as a dialog. Can we set the width and hieght for that
