.scrollTo times out in kitchensink tests

[jennifer-shehane]

This .scrollTo() times out very frequently in the kitchensink tests. Sometimes the bug shows up as a .screenshot() timeout after the scrollTo fails.

Seems to fail mostly in CircleCI Mac, Electron and also in Windows Appveyor.

CircleCI failure: https://app.circleci.com/pipelines/github/cypress-io/cypress-example-kitchensink/1063/workflows/081e2595-85f7-4cc9-a5f7-fa3f23006b8e/jobs/6905
