What steps will reproduce the problem?
(1) Open http://w3c-test.org/dom/nodes/Document-characterSet-normalization.html in Chrome.
(2) Observe the test results.

What is the expected result?
All the tests should pass.

What happens instead?
Three tests fail:
Fail	Name "Shift_JIS" has label "ms932" (characterSet)
	assert_equals: expected "Shift_JIS" but got "windows-1252"
Fail	Name "Shift_JIS" has label "ms932" (inputEncoding)
	assert_equals: expected "Shift_JIS" but got "windows-1252"
Fail	Name "Shift_JIS" has label "ms932" (charset)
	assert_equals: expected "Shift_JIS" but got "windows-1252"

Per https://encoding.spec.whatwg.org/#names-and-labels ,
"ms932" is a label for Shift_JIS, not for windows-1252.
