Free version, I create a new workspace and a new board in this workspace with visibility Workspace visible. This visibility setting's description is:

"AII members of the <name> Workspace can see and edit this board."
I invite someone to the workspace, they can see the board but can't edit it. If I then also invite them to the specific board, they can also edit it.
Is this behaviour expected? This is actually what I want (workspace members being able to view but not edit) but from the description I get that they should also be able to edit just by being in the workspace. I don't want to rely on a temporary bug or something.
