ComboBoxes provided by UI frameworks normally show their selection possibilities once focused, ExtJS does this too but not on editable (and thus filterable) input fields. Add a logic which allows this too and streamlines the behavior of ComboGrid/Box like components. To avoid a glitch, where clicking the "picker trigger" (the down arrow which normally toggles the selection picker) would first focus the element - thus expanding it - and only then causing a toggle which collapses it again, we overwrite the 'Ext.form.trigger.Trigger' onMouseDown so that we can skip a expansion on this event.
