    inhibitShortcutsDialog: Enable line wrapping for additional label
    
    The inhibitShortcutsDialog can show an additional label which explains
    how to restore shortcuts. This label is not managed by the
    MessageDialogContent, so we need to enable line wrapping and disable
    ellipsization ourselves.
