Cloud Code breaks multibyte? yaml editing

- Cloud Code for IntelliJ version: 23.6.3-IB.1-api-version-222
- Google Cloud SDK version: 438.0.0
- OS: Windows 11 10.0

**What did you do?**
Editing UTF-8 YAML containing Japanese text.

**What did you expect to see?**
No code problems are shown.

**What did you see instead?**
Many unexpected code problems are shown:

YAML is basic and should be valid:
```yaml
test:
key: value
foo:
key: value

キー: 値

bar:
key2: value2
```

I tried this with IDEA 2023.2 Beta (Ultimate) `#IU-232.8660.48` only for now, and I don't know if it's related to Beta/EAP or not.
(I'd like to note that this problem can't reproduce if I disable the Cloud Code plugin)
