Just double checking that it was expected for this test's output to change as well.

I am not entirely sure why this changed (not sure why it was how it was before this PR) but yes this is the expected output

Closes #633.
Previously, using
waitForonly would return values if they were serializable. (The new test would fail,waitForwould returnundefined). This is because our implementation ofwaitFordefers to Testing Library's in-browser implementation (uses MutationObserver + timers to watch for changes). Previously the return value got passed to the browser and back.In this PR, I changed the return value from the callback to never go to the browser and back, it just stays in node, so we don't have to worry about serialization or deserialization.
