Describe the bug you're encountering

Our Swagger UI React is wrapped under React Hook Form and whenever the Swagger expand spec is clicked (The down arrow) the whole form submits, this is because of missing type attribute in native <button> element. Request you to add type on your buttons like <button type="button" > to avoid any default submission.

This is a sample element currently -

To reproduce...

Steps to reproduce the behavior:

1. Go to Pet Store
2. Click on Inspect Element of "Down Arrow" of any endpoint like '/pet/{petId}/uploadImg
3. Scroll down to the HTML Button element and see there is no Type attribute
4. See missing attribute

Expected behavior

the tag should be present with attribute so that any Swagger UI under form submission works properly

Additional context or thoughts

Start by reproducing the issue in the Swagger UI React interface using the Pet Store example, then inspect the rendered expand-spec button shown in the report. Ensure the affected native buttons explicitly declare their intended type, and verify that expanding an endpoint inside a form no longer submits it.
