PR #1032 fails Cyress custos-drag test when run as github action, but passes when run locally

For some reason, the custos drag test fails when the Cypress github action is run (upon making a PR). However, when I run the same tests locally, they all pass.

I believe the issue has something to do with the virtual viewport size used in the tests. My local size is 1000 (width) by 600 (height) pixels.

Start by locating the Cypress custos-drag test and the GitHub Action that runs it. Compare the action's virtual viewport with the reported local 1000x600 viewport, then reproduce the failure in CI. Done means the custos drag test passes reliably in the GitHub Action as well as locally.
