SinkBinding does not clear NoAddressable

[Evynglais]

Describe the bug
When we create a ContainerSource before creating it's corresponding sink, the SinkBinding correctly goes to NoAddressable; however, this frequently fails to clear when the sink becomes available, and does not get resolved within a reasonable time limit (we have monitored for 10m before manually intervening).

Restarting the eventing-webhook pod immediately resolves the SinkBinding status, which in turn is reflected on the ContainerSource.

Expected behavior
The NoAddressable status on the SinkBinding (and ContainerSource) should clear once the addressable becomes available.

To Reproduce
Install a ContainerSource with a missing sink. Create the sink. Sometimes the status of the ContainerSource and SinkBinding will update; sometimes it will not.

Knative release version
Operator 1.22.3

We've also noticed that sometimes the K_SINK does not get injected into the ContainerSource (which is left in an unrecoverable state) when the sink becomes available, but we're not sure if this is the same issue or something else.
