The following tests are flaky timeouts on iOS with decoding error starting 299614@main.

+FAIL: Timed out waiting for notifyDone to be called
 Ensures a renderer will decode its image synchronously if it intersects with another renderer with a different sizeForDrawing.
 On success, you will see a series of "PASS" messages, followed by "TEST COMPLETE".

The first failure is with 299615@main, and these tests are extremely flaky. Given that many preceding revisions are definitely unrelated, 299615@main seems like the most likely culprit, even though not obviously related either.
