Sharing the current state of my investigation:

The ContentStateReducer is called once with UpdateTitleAction, that set the right title to the state.

But it seems like, in the website impacted by the bug, the ContentStateReducer is called with UpdateUrlAction after it has been called with UpdateTitleAction.
As the URL has changed, the title is set to null here.

I'm not sure yet if the problem is the order in which the actions are passed to the reducer, or that some UpdateTitleAction are missing after the UpdateUrlAction happened.

I'll continue investigating next week.
