[list-separator] TypeError when reading 'split'

[C-Ezra-M]

Somehow, this happened unexpectedly in a Mavo app I'm making. I used the codebase as if mavoweb/mavo#1025 was already merged, as Netlify is deploying it for use with a <script> tag.

mavo-list-separator.js:22 Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'split')

Hey there,

Thank you for reporting the bug. I’m planning to give it a closer look ASAP. Is there a chance you could share a piece of your code causing the bug, e.g., on Codepen? It would help us to narrow down the issue tremendously.

Somehow, that issue was caused by having incomplete initial data (i.e. all but one property were excluded). And unfortunately, I can't easily reproduce this bug since it's inconsistent. However, it does sometimes cause multiline input to be pasted twice.
