WPT test for Blob constructor has unexpected behaviour

[izgzhen]

In tests/wpt/metadata/FileAPI/blob/Blob-constructor.html.ini, the second test:

 [Passing an platform object that supports indexed properties as the blobParts array should work (window).]
expected: FAIL

you can delete this line, modify it to PASS or whatever else, the test will still pass.

Look at the tests/wpt/web-platform-tests/FileAPI/blob/Blob-constructor.html and we found:

test_blob(function() {
  var select = document.createElement("select");
  select.appendChild(document.createElement("option"));
  return new Blob(select);
}, {
  expected: "[object HTMLOptionElement]",
  type: "",
  desc: "Passing an platform object that supports indexed properties as the blobParts array should work (select)."
});

First, it is select but not window, but even if I changed the select to window, the test is still not working.

Ok ... I found another one testing select ... I will fix the test script later

@Ms2ger [Passing an platform object that supports indexed properties as the blobParts array should work (window with custom toString).] and [Passing an platform object that supports indexed properties as the blobParts array should work (window).] seem not existing in the Blob-constructor.html anymore. Should I delete the corresponding testing entry?

(BTW, looks like the ./mach test doesn't complain even if some test in ini doesn't exist)

Yes, INI entries that don't correspond to actual tests are ignored by the test harness. It can lead to confusion, but I'm not sure if it's a big deal.

[izgzhen]

@jdm Ok, if "nothing happens" == "everything is good" then then it looks sensible to ignore it. I will fix this manually later.
