What happened + What you expected to happen

Create Parent/Child Deployments, manually assign both the same name, in this case "common", and pass the Child as a __init__ arg to the Parent. Serve detects a name conflict and renames one of the deployments "common_1", but serve.run(...) incorrectly binds to the Child app even though it's called with the Parent app as an explicit argument. I'd expect the return value of has_child to be True, but it's False.

repro

from ray import serve
from ray.serve import handle

class Repro:
    def __init__(self, child: handle.DeploymentHandle | None = None) -> None:
        self._child = child

    async def has_child(self) -> bool:
        return self._child is not None

@serve.deployment(name="common")
class Parent(Repro):
    ...

@serve.deployment(name="common")
class Child(Repro):
    ...

app_dh = serve.run(Parent.bind(child=Child.bind()), blocking=False)

# call
print(f">> has child: {await app_dh.has_child.remote()}")

Of note, you'll get the correct result if you remove name="common" arg from the serve.deployment decorator as the Deployments will have unique names.
