YAML editor - disappearing text with autocompletion

I found an issue while creating the yaml editor. The editor uses the codemirror-json-schema library for validation and autocomplete.
When I start typing the first valid keyword and select a suggestion from the autocomplete, some text below disappears.

In the other lines everything is fine.

I created a simple project where you can reproduce the problem:

I’m not sure if it’s a Codemirror or codemirror-json-schema issue.
Any ideas?
Thanks

I’d lean towards suspecting codemirror-json-schema, but if you can reproduce something like this without 3rd-party extensions let me know.

Thanks for reply.
