Refs #31820.

This PR updates repl evaluation to eagerly wrap all input in parentheses and adds a regression test using the example given in the above issue. I plan to open a follow-up PR to allow the preview to evaluate the code again unwrapped if the first attempt fails.

I don't think there's an immediately obvious behaviour to have here so just aligning the two evaluators is good enough imo.

LGTM besides the mentioned whitespace issue. It should be handled identically when previewing and actually evaluating the code.
