I answered the question myself.

The test needs a placeful setup instead of a placeless setup. There is a
method in zope.app.testing.setup that does everything needed.

Change to:

...
from zope.app.testing.setup import placefulSetUp

def setUp(test):
    test.globs = {'root': placefulSetUp(True)} # placeful setup
    zope.component.eventtesting.setUp(test)
    zope.component.provideHandler(updateWeightedItemsContainerOrder)
    vocabulary.setVocabularyRegistry(vocabulary.VocabularyRegistry())
    vr = vocabulary.getVocabularyRegistry()
    vr.register('quotationtool.categorization.categorizableitemdescription',
                categorizableItemDescriptionVocabulary)
    vr.register('quotationtool.categorization.mode',
                modeVocabulary)
    vr.register('Interfaces',
                InterfacesVocabulary)
