Supercedes #3775
This PR bumps our vendored
web-vitals
to version2.1.0
. As this bump updated the definition of CLS, we now track the old CLS definition (cls
measurement) and the new CLS definition (updated-cls
measurement) in the transaction.We will then cut a beta off this branch and test on Sentry for a couple days. If there isn't a huge discrepancy, we will remove the old CLS definition and move the
cls
measurement to rely on the updated CLS definition.Aside from vendoring web-vitals, we also introduced a changelog and noted down the differences between the
web-vitals
npm package and our vendored version.TODO:
