Note that for the integration tests the coverage information ends up being processed in the Node.js context where `window` is not available, so we use `globalThis` instead for the function that merges individual test's coverage information into the global object because that is available in all contexts we support. For clarity we also rename said function since we're not exclusively dealing with `window` nor worker data anymore.
