Web Benchmarks failing #411
Description
Unsure what started this issue, but the web benchmarks seemed to have stopped working.
I submitted an almost empty PR to reproduce: #410. Thinking it might've been some dependency problem issue, I ran flutter pub get which updated the version for the transitive webdriver dependency. This caused the Mac bot to fail similarly to how the Windows bot was failing when I first spotted the issue (see my next comment for what shows on the Windows bot without any changes to pubspec.lock).
