Custom converter with attributes/injection not working with anymore after upgrade to JSF 2.3 - cdi

Question

I am trying to upgrade/use a custom converter that worked with JSF 2.2 (on Wildfly 13) to work on JSF 2.3 (with Mojarra 2.3.9.SP02 running on Wildfly 17.0.1)
The converter is used via its own tag defined in a tag library.
Everything's fine as long as no tag attributes are used. The attributes are just not set in the converter. The setters never get called.
But if I remove the managed = true from the converter the attributes are set but then the injection no longer works.
The converter is used like this:
<h:inputText id="text" value="#{welcome.text}">
<cdijsf:converterWithAttr id="myConverter" attr="myAttrValue" />
</h:inputText>
Tag library:
<facelet-taglib version="2.3"
xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-facelettaglibrary_2_3.xsd">
<namespace>http://cdijsf.transdata.net/jsf</namespace>
<tag>
<tag-name>converterWithAttr</tag-name>
<converter>
<converter-id>cdijsf.ConverterWithAttr</converter-id>
</converter>
<attribute>
<name>attr</name>
<type>java.lang.String</type>
</attribute>
</tag>
</facelet-taglib>
And this is the converter code:
#Dependent
#FacesConverter(value = "cdijsf.ConverterWithAttr", managed = true)
public class ConverterWithAttr implements Converter<String> {
#Inject
private BeanManager beanManager;
private String attr;
public ConverterWithAttr() {
}
#PostConstruct
private void init() {
// If 'managed = true' beanManager is injected at this point.
// If 'managed = false' beanManager is null at this point
}
#Override
public String getAsObject(FacesContext context, UIComponent component, String value) {
return value;
}
#Override
public String getAsString(FacesContext context, UIComponent component, String value) {
return value;
}
public String getAttr() {
return attr;
}
public void setAttr(String attr) {
// If 'managed = true' setAttr is never called
// If 'managed = false' setAttr is called
this.attr = attr;
}
}
faces-config.xml:
<faces-config version="2.3"
xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-facesconfig_2_3.xsd">
</faces-config>
And I also explicitly declare JSF 2.3 like this:
#FacesConfig(version = Version.JSF_2_3)
#ApplicationScoped
public class JsfConfiguration {
}
beans.xml:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/beans_2_0.xsd"
version="2.0"
bean-discovery-mode="annotated">
</beans>
