Trying to use // !JSCRIPTVER=3

In the latest DOpus I read in the release notes that // !JSCRIPTVER=3 has been added to enable newer script features on Windows 11. I'm on Microsoft Windows 11 Pro 10.0.22631 N/A Build 22631 and was hoping this bit of script would work, but it throws an error. Am I misunderstanding something here? Thank you.

// !JSCRIPTVER=3
function OnInit(initData)
{
	initData.name = "wibble";
	initData.version = "1.0";
	initData.copyright = "(c) 2025 wildw";
	initData.desc = "wibble";
	initData.default_enable = true;
	initData.min_version = "13.0";
	var mystring = " Wibble ";
	DOpus.Output(mystring.trim());
}
wibble.js:  Error at line 11, position 2
wibble.js:  Object doesn't support this property or method (0x800a01b6)

I haven't found any documentation that categorically states when the JScript engine was updated, so I'm guessing your version of Windows is too old.

On Version 10.0.26100.2605 here and I get:

OK, thanks for checking, Jon. 22H2 is build 10.0.22621 and I am on 10.0.22631 but you seem to be further ahead again.
