The new SpokenFeedbackTest.ChromeVoxApi test added in https://chromium-review.googlesource.com/c/chromium/src/+/847896 is crashing on the linux-chromeos-dbg builder (https://ci.chromium.org/buildbot/chromium.chromiumos/linux-chromeos-dbg/3567).  I'm going to revert the CL.

Here's the dump from the test logs:
