One big thing to note, Enter can no longer be used to toggle a switch or checkbox with this PR. It could be argued that Space should be the only way to do it as that is how native inputs work, but we've had this behaviour for 6+ years, so I don't know if we can change it lightly.

I hadn't noticed this impact.

I think disabling Enter-to-toggle is necessary to properly address this issue, because allowing Enter to both toggle a checkbox/radio/switch and submit a form at the same time feels like unexpected behavior.

How should Enter be handled for these elements...?
