1. Open http://w3c-test.org/dom/nodes/Element-classlist.html 2. Observe "classList.replace("a", "a") with attribute value "a a a b" (HTML node)" test. This test fails with the following message: > assert_equals: wrong class after modification expected "a b" but got "b" Existing "a" token was unexpectedly removed.

Pass classList.replace("a", "a") with attribute value "a a a b" (HTML node) So presumably this has already been fixed?

I am confirming. I can reproduce the bug with shipping Safari but not with Safari Technology 30 (which is not even the latest one).

Oh, I tested with Safari TP 29. Sorry for the noise.
