conan: conan install -u not updating indirect aliases

• Conan Version: 1.7.4

Background:

• There exists a library libA/1.latest@demo/test which depends on libB/1.latest@demo/test
• I am building a package which depends on libA
• The libraries use self.requires("...") for specifying dependency

Scenario:

• I build my package
• Now libB and libA both aliases are updated to newer packages
• I do a conan install .. -u, it fetches new libA, but uses older libB alias

I suppose this is because I do not specify libB directly as dependency.
Am I missing something? Or is this a bug?
