Slug sometimes not slugging

[bobdenotter]

Sometimes (I've seen it twice, and also reported by @peterboorsma), the slug doesn't generate.

For the same site, my local setup works:

But on production it doesn't work:

The contenttype is pretty straightforward:

news:
    name: News
    singular_name: Newsitem
    recordsperpage: 5
    fields:
	title:
            type: text
            class: large
        image:
            type: image
        content:
            type: redactor
       	slug:
            type: slug
            uses: title

Could this be related to issue #1784, not detecting that "title" is indeed a valid field to generate the Slug from? 🤔

Some additional findings: For me it happens on new Records.. If I edit an existing one, i can select the "Generate from title" option as expected:

However on new Records, it breaks. It seems to go wrong in the step generating the HTML. Not the generate attribute in these screenshots from working vs non-working similar setups:
