Accepting cookies services one by one will automatically deny consent functional cookies

Mhm this is really strange and I'm unsure about the consequences. How can I see that the consent is denied technically? JS callback?
Do any services actually listen to this in reality?

The cookie value for "functional" will be false.

Accepting / Denying ALL cookies sets it to "true" / "false" as expected. This is only the case, when setting it via the "Cookie Settings" dialog.

@JFeltkamp I think this needs to be fixed in cookiesjsr?

#3323044: [2.x] Use the Cookies service "Consent required" value and add tests → seems related?
