There are around 40 test classes in the flow repository alone where Label is used. Looking quickly many tests are using Label in a wrong way, meaning they should be really just Span or Div instead. However, as Label will be deprecated and NativeLabel is direct replacement, then all these tests should be changed to use NativeLabel and make sure tests still works.

I suppose that before adding a new listener by beforeClientResponse, it should check

if (checkForAttributeOnAttach == null) { 

otherwise I don't understand why we use beforeClientResponse at all.

The build validation stops because of compilation errors:

Error:  Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.11.0:compile (default-compile) on project flow-html-components: Compilation failure
Error:  flow/flow-html-components/src/main/java/com/vaadin/flow/component/html/Label.java:[184,33] cannot access jakarta.servlet.http.HttpSessionBindingListener
Error:    class file for jakarta.servlet.http.HttpSessionBindingListener not found

This pull request doesn't add/import this class, this is weird.

@mshabarov I just realized that there are a lot of usages within the flow-components that are still using the old Label and polluting the logs because they are not associated on the server side, but on the client side thanks to the slot=label Attribute. I'm wondering if we should add this condition also to the list of valid usages to reduce the amount of work the component team has to do urgendly to remove the log spam for users.

Example FormLayout or RadioGroup
