What happened?

const props = { type: "submit" as const };
return <button {...props}>button</button>;

Biome should be able to tell that the type prop is spread onto the button element but it is still reported as an error in the lint/a11y/useButtonType rule.

Expected result

It should not raise any error.

Code of Conduct

• I agree to follow Biome's Code of Conduct

[Sec-ant]

I think this is an expected limitation because of a lack of type inference as of now.

[ematipico]

Yeah, that's a bug. If there's a spread prop, we shouldn't trigger the rule
