When looking up an attribute with .attr(), the name of the attribute should be lowercased before looking up in .attribs object.

I use some facebook markup that I let facebook parse from DOM:

      <fb:login-button 
        auto-logout-link="false"
        button-type="continue_with" 
        size="large"
        scope="public_profile,email" 
        use-continue-as="true">
      </fb:login-button>

In my onMount I then let the facebook API do it's thing with th

fd = new FormData
fd.set('a', new Blob)
fd.get('a') === fd.get('a') // false in chromium - true in FF & Safari (don't have IE on Mac)

Looks like there is no test to cover this senario: https://github.com/web-platform-tests/wpt/blob/e45a9f9e65d039c76817ee2a6a1ef02c9311a1cb/xhr/formdata/set-blob.any.js
