Lists with "Hide from home" do not retroactively include a user's posts nor hide them from home

[Thibaulltt]

Steps to reproduce the problem

1. Create a new, empty list.
2. Add one or more users (visible from your home timeline) to that list.
3. Enable the option "Hide these posts from Home".
4. Refresh the page, and notice the older posts from that/those users still appear on the home timeline.

Expected behaviour

When adding a user to a "hide-from-home" list, their posts should only be visible from that list.

Actual behaviour

The older posts by those users stay on the home timeline. Their new posts, however, are in the list.

Detailed description

The official documentation does not indicate that the lists only fetch the content of a user's post from the moment they are added to the list onward, so it seems like an issue ?

Regardless of what the documentation says, I expect all of a user's posts/contents to be visible from a list they are added to, and if that list is hidden from my home timeline then none of their posts should find their way to it.

Partial duplicate of #13867 -- the larger issue is that lists don't update retroactively in general.
