It seems like type="button" should be coming from the call to useButton, but I haven't tracked down why the type attribute doesn't come through in the button props.

Also strange here is the type="button" does apply to the button in the test environment even without these changes.

Actually thanks to your comment about how type="button" was getting applied in the tests I dug around a bit more and found that this already has been fixed by #5958. Since this PR was made after the last release so you'll have to wait until our next release to get this update. We're hoping to get one out by the end of next week since it has been awhile but I can't guarantee anything. I think you can close out this PR but thank you for taking the time to work on it and submit it!

Ah, thanks for the update. I realized soon after typing that comment about the tests that the issue had likely already been fixed. I wasn't sure where, though.
