Exclude omitted dependencies as well through a second cycle

[timtebeek]

What's changed?

Run a second cycle of ExcludeDependency when the document has changed, to also exclude previously omitted dependencies.

What's your motivation?

• Fixes Also exclude omitted dependencies #4563

Anything in particular you'd like reviewers to focus on?

Second cycle might require changes in the future, but at that point we're more free to change the model as well, as seen in:

• Also exclude omitted dependencies #4563

Anyone you would like to review specifically?

Have you considered any alternatives or workarounds?

We can change the model as seen in this work

• Also exclude omitted dependencies #4563

But that would then need careful consideration to account for serialization, and we'd be doing so for a single use case here.

@timtebeek Thanks for your deep check and fix! Nice to see the issue fixed. That's really a helpful recipe for us.
