The ARIA Authoring Practices guide is not normative (i.e. it is not a
fflat out violation when its recommendations are not followed).
That being said, it is the model that we should always follow whe
constructing custom components.
When there is a significant deviation from that spec we should explore
it, ask ourselves if the users are likely to be affected, and file an
issue if we feel this is the case.
In this case, the spec recommends that the focus order is trapped
inside the dialog, as you describe very well.
I don't know why the focus is escaping out to the address bar, it does
ot in this example for instance:

What browser are you using? It could be a browser thing.
