mutate_reactive doesn't work with data binding

[Banbury]

Description

mutate_reactive doesn't execute watchers in components, that are connected via data binding. I am using a reactive list in the app. I have bound this list to another reactive list in a child component. When I execute self.mutate_reactive the watcher in the app is called, but the watcher in the child component is not.

Can you give us an MRE? https://label.dev/articles/minimal-reproducible-example/

Maybe on the weekend. But all that is needed is an app, a widget, two reactive lists and two watch functions.

Assuming this is the same issue https://github.com/Textualize/textual/issues, it will be fixed next release.
