DOM's initEvent says that it must do nothing during dispatch. UI Events says they behave the same as initEvent, so the legacy initializers defined there also shouldn't do anything during dispatch. Previously we only did this for initEvent itself, but other legacy initializers would function normally during dispatch. Edge passes the wpt test that's updated in this commit. Chrome passes all but initCustomEvent. It would be nice to expand the test to have coverage for all our legacy initializers, but the likelihood of real-world compat issues from this behavior is slim enough that I didn't think it was worth the effort.
