This looks like it may have regressed around 254399.
r254399 is when a new version of this test and its expected result was first landed, so there’s no reason to think this became more flaky because of a software change. It’s just that the new part of the test is flaky. And what seems flaky is the question of whether a type error is logged to the console. I wish I knew more about where the type error was coming from, even which JavaScript source file.
