@slovnicki Can you take a look at the PR, when you find some time? :)

LGTM ✅

Hey @fabianbrandscheid 👋
Thank for the PR!

I see some issues, will look into it later today or tomorrow.

@slovnicki Thank you!

When you need some help, feel free to contact me :)

@fabianbrandscheid I now fully understand the need for this functionality.
I've been able to create a use case where we need to update browser title and there is no other way except having html.document.title = title; in one's project.

The use case is when we are doing Beamer.of(context).update(... rebuild: false). Route information (URL) is updated correctly, but browser title not because it gets called only during build (which is a mistake).

This tells me we should call setTabTitle in updateand not inbuild` so I would rewrite this PR differently. Let me know if you're ok with me closing this and we can open a new one.
