Javascript js files are not added into qmldir with qt_add_qml_module

I am creating a Qt6 QML module with qt_add_qml_module.

qt_add_qml_module(SQUtils_Logger_Qml
 URI SQUtilsLogger.Qml
 VERSION 1.0
 SOURCES
   LoggerQml.cpp
 QML_FILES
   Log.js
   Logm.mjs
   LoggerQml.qml
 )

But the generated qmldir contains only the information about the qml file: the js and mjs files are missing.

module SQUtils.Logger.Qml
linktarget SQUtils_Logger_Qmlplugin
optional plugin SQUtils_Logger_Qmlplugin
classname SQUtils_Logger_QmlPlugin
typeinfo SQUtils_Logger_Qml.qmltypes
prefer :/SQUtils/Logger/Qml/
LoggerQml 1.0 LoggerQml.qml

It is a problem because when I run "ninja all_qmllint", the compiler/linter complains that Log is not defined:

// View.qml
import SQUtils_Logger_Qml
//import "qrc:/SQUtils/Logger/Qml/Log.js" as Log
ApplicationWindow {
 Component.onCompleted: {
 Log.debug("QML main application complete")
 }
}

Warning: View.qml:120:13: Unqualified access
 Log.debug("QML main application complete)

If I append "Log 1.0 Log.js" to the qmldir file, then the lint works.

What I am doing wrong? Is this a bug? The qt documentation for qt_add_qml_module indeed quotes:

QML_FILES lists the .qml, .js and .mjs files for the module. [...] 
The files will also be used to populate type information in the generated qmldir file.

Thank you for your help!

Note: I can manage to run my code by uncommenting

import "qrc:/SQUtils/Logger/Qml/Log.js" as Log

but the lint still does not work.
