No cursor when content is empty

[Kasheftin]

Describe the issue

There's no blinking cursor when the content is empty & editor is focused.
There's something wrong with the .cm-cursor div height, it's zero.
Here's the trivial source code and the repro, https://github.com/Kasheftin/codemirror-no-cursor-bug.
It looks like a recent change somewhere, because I have several projects using codemirror, and everything is working fine there.
Codemirror v6.0.1.
vue-codemirror v6.1.1.

Browser and platform

Ubuntu, Chrome Version 113.0.5672.126 (Official Build) (64-bit)

The problem does not occur in a simple setup. Could this be related to the Vue wrapper?

[Kasheftin]

I updated the demo, and it shows that the raw codemirror v6.0.1 works correctly.
Posted an issue there, surmon-china/vue-codemirror#201.
