Bug: Unit testing error message - "The tag <search> is unrecognized in this browser. If you meant to render a React component, start its name with an uppercase letter."

[IsaacMcIntyre]

React version: 19

Steps To Reproduce

If using my linked example:

1. Create component that uses the search component
2. Create a unit test that renders this
3. Run the test

Link to code example: https://github.com/IsaacMcIntyre/search-tag-testing-bug

The current behavior

Test runs with no errors

The expected behavior

Test passes, but with console error:

console.error
   The tag <search> is unrecognized in this browser. If you meant to render a React component, start its name with an uppercase letter.

     4 | describe("SearchComponent", () => {
     5 |   it("renders", () => {
   > 6 |     render(<SearchComponent />)
       |           ^
     7 |   })
     8 | })

Other Context

I've seen similar issues written in the past for and where they are not inside an tag, but from my understanding there should not be any requirements of elements outside or inside the search tag. With this being a relatively new html element, I'm wondering if this is just something that needs updating? Or am I doing something wrong?

Apologies if this is the wrong place / I have misunderstood something.

Thanks!
