AustinMroz 3164e6ab61 On workflow swap, restore 'Preview as Text' text (#13536)
Also adds proper typing for `onNodeOutputsUpdated`

See also: #12877 and #13427, which include near equivalent changes for
the bug itself, but different tests. If I had more time and had not
already made my own fix, I would have liked to spend more time getting
either of them cleaned up.
