FileInput no longer passes source to name attribute, and instead id attribute

[andrico1234]

FileInput no longer receives a name attribute. Instead it gets passed an id attribute instead.

The main problem for us is that it causes our E2E tests to fail (though this is something we will happily update), it also means that there are elements with duplicate IDs (HTML validation issue). e.g.:

This is a problem that exists in the CodeSandbox without any changes needed.

Just jump into the Create Post page. Open the element inspector and move to the input type="file" element, and observe the problem
