setHideTrigger problem

[nproto]

When I use setHideTrigger to hide the trigger in a combobox the combo becomes invisible.
In the vbox-form example if you add

listeners: { 'afterrender': function() {
this.setHideTrigger(true);
}
}

in the email combo the combo becomes invisible.
The problem exist with version extjs 4.1.0-beta-1 and not with extjs 4.0.7-gpl

I checked with the firebug an found that the whole table containing both the field and the trigger is set to display: none (<table id="combobox-1015-triggerWrap" class="x-form-trigger-wrap"...)
Has anybody experienced the same problem?

We've run across this one during testing, should be fixed up for the next release.
