Describe the bug

After the update to v1.1.0 our dashboard with a host groups view ins't showing the names of the host groups anymore. They are being cut off.
This happens when adding the view to the default "Current Incidents" dashboard as well as to our own "custom global dashoard" deployed via a module

<?php

$dashboard = $this->dashboard('OPS', ['priority' => 0]);
$dashboard->add(
    'Taktische Übersicht MSD only',
    'icingadb/tactical?host.name_ci~msd%2A'
);
$dashboard->add(
    'Übersicht Hostgruppen',
    'icingadb/hostgroups'
);

?>
