Looking at the most recent 200 runs, there are quite a few timeouts in this builder: https://ci.chromium.org/ui/p/flutter/builders/prod/Windows%20tool_integration_tests_2_7?limit=200

The timeout appears to be 45 minutes, but I thought most of our CI tasks had a timeout of 60 minutes. Perhaps we should consider increasing the timeout to 60 minutes, or possibly breaking this group of tests into more shards
