pullDownHeight is not working in the configuration object

[WaldemarEnns]

I tried it just like the documentation tells me to do:
config: { pullDownHeight: 20 }

Doesn't work, seems that it gets completely ignored.

Here is my setup:

<vue-pull-refresh :on-refresh="loadNewImages" :config="pullConfig">...</vue-pull-refresh>

...

<script>
...
pullConfig: {
                    errorLabel: "Beim Laden der Bilder ist ein Fehler aufgetreten ...",
                    startLabel: "Bilder nachladen",
                    readyLabel: "Zum Nachladen loslassen",
                    loadingLabel: "Lade Bilder ..."
                },
...
</script>
