subMap not recognized as a valid method for record types

According to the records documentation, subMap is a valid method for the record type.

When using the Nextflow extension, this is not recognized and the workflow is highlighted as having an error.

The error given is: Unrecognized method subMap for type Record

Code to reproduce:

nextflow.enable.types = true

workflow {
	main:

	def x: Channel<Record> = channel.of(
		record(id: "example", value: "value1"),
		record(id: "example2", value: "value2")
	)

	x.map{r: Record -> 
		def y: Record = r.subMap(["id"])
		println("y: ${y}, type: ${y.getClass()}")
	}

}

This does run through nextflow fine:

WARN: Static typing is a preview feature -- syntax and behavior may change in future releases
y: [id:example], type: class nextflow.util.RecordMap

Nextflow version: 26.04.6
Language-server version: 26.04.2
VS Code extension version: 1.7.1

Reproduce the diagnostic with the provided typed Nextflow workflow using the listed language-server and VS Code extension versions. Trace how the language server recognizes methods for the Record type and compare that behavior with the records documentation and successful Nextflow run. Done means subMap is no longer reported as an unrecognized method.
