integration tests failing with "(-32000) Service connection disposed" #155475
Description
I believe that this is the root cause of #153578, which was that MANY integration tests in the flutter/packages repo were timing out. After I landed #154970, these should no longer time out, and I found https://logs.chromium.org/logs/flutter/buildbucket/cr-buildbucket/8736798859005867345/+/u/Run_package_tests/drive_examples/stdout, which from the stacktrace would have timed out before my change.

I'm also seeing this in a lot of devicelab tests in the flutter/flutter repo:
