To my enormous relief, the Samsung stove that came with our house gets this right - even covered in water the controls still work. I was previously dead-against induction just because I couldn't find a good quality stove-top with physical buttons, to the point where I'd already budgeted replacing it with gas when we bought the house. I don't know how they've done it, but it's the only one I've ever used that manages. (For comparison, the high-end Miele and cheap-and-cheerful non-branded ones I've used in various rental houses over the last 20 years have all had exactly the problem you describe above).
