I followed a notification link to a topic page, and found myself unable to reach the associated content page by clicking on a tab. This is, as I understand it, a departure from our current user expectations, and a hindrance to existing workflows.
- Adding tabs, like LQT does. (E.g. "Namespace" + "Discussion namespace" + "Topic").
- Adding to the existing breadcrumb links. (E.g. by changing < [[Talk:Sandbox]] to something like < [[Talk:Sandbox]] ([[Sandbox]])
We need to take the planned T109642: Provide cross-board Flow topics and also T68779: Provide cross-wiki Flow topics into account.
A topic could be attached to multiple Boards, at multiple wikis. (although they will probably have a "primary" location)
