Before this commit, the process of positioning chat windows
could fail if one of the tabs had discuss open.
When a chat window was hidden and become visible, the algorithm
was not updating the state of the chat window to "visible" when
discuss was open. As a result, it was always trying to make it
visible, resulting in an infinite loop and raising the following
error message:
`Uncaught RangeError: Maximum call stack size exceeded`
This commit ensures it works even when discuss is open.
