NetBeans 13 XML folded blocks automatically unfolding

### Apache NetBeans version

Apache NetBeans 13

### What happened

Hi,

I've recently started using NetBeans for XML file editing. I've installed the latest version and have an issue with even simple XML files. I have not added any plugins and since I have only just started using NetBeans I don't know if this happened in previous versions.

I am finding that nodes that I have folded automatically unfold whenever I start to edit a different node. It doesn't seem to be time related and the nodes I am editing are NOT part of the node that automatically unfolds.

I initially installed NetBeans on my Linux VM and thought it might be an issue there, but the same thing happens with a fresh install on evil Windows 10.

I tried creating the simplest XML file:-

```

```
If I collapse the "``" node, then click my mouse on the end of the "``" row, hit enter, or paste some text, the collapsed "``" node automatically un-folds.

I've tried different versions of the jdk using --jdkhome command line option. I have also tried using a completely new --userdir directory, the same thing keeps happening, so I assume it can't be an option I have set.

I've attached a screen record of it happening of the evil Windows installation.

### Are you willing to submit a pull request?

No

### Code of Conduct

Yes

Reproduce the issue with the minimal XML file described in the report: collapse the node, then edit the separate row. Start by tracing the NetBeans XML editor's code-folding behavior; done means the collapsed node stays folded after clicking, pressing Enter, or pasting elsewhere.
